Greetings from the
Chairmen of the Symposium
Dear Colleagues,
We are pleased to welcome you to the joint International Symposium on Frontiers in
Applied Mechanics (ISFAM 2014) that will take place in Singapore on 4-7 Dec. 2014
(http://www.acmsg.org/ISFAM2014.htm). The symposium follows the style of Gordon
Research Conferences. This major event has been organized by the Association for
Computational Mechanics (Singapore), the International Center for Applied Mechanics
(XJTU, China), the Theoretical and Applied Mechanics Society (Singapore), Department
of Mechanical Engineering (NUS, Singapore), and School of Mechanical and Aerospace
Engineering (NTU, Singapore).
The symposium topics cover most disciplines on the conventional subjects of solid
mechanics and fluid mechanics, as well as current topics associated with applied
mechanics, which covers inter-disciplinary areas such as nanomechanics, biomechanics,
electromechanics, mechanics of advanced materials and soft matter, and numerous other
emerging areas. This symposium aims to cover the recent progress made in all these areas.
Hailing from China, Hong Kong (China), Singapore and Australia, distinguished
scientists, academics, researchers and engineers from over 30 institutions will gather in
Singapore to present their work, and preview the latest developments in the many
different topics on offer. In particular, we also eagerly look forward to the meeting with
old and new colleagues.
We have also planned a welcome reception on Thursday (Dec. 4th
), the banquet on Friday
(Dec. 5th
) and get-together party on Saturday (Dec. 6th
).
Above all, we want to thank you for your participation and contribution to the
symposium and express out best wishes for a fruitful scientific, technical and personal
experience during the four days of the meeting.
Last but not least, we wish you a most enjoyable stay in Singapore.
Your Sincerely,

Green’s Functions of the Forced Vibration of Timoshenko Beams with Damping
Effect
X.Y. LI
School of Mechanics and Engineering, Southwest Jiaotong University, Chengdu, China
zjuparis6@hotmail.com
Abstract:
Our work is concerned with the dynamic solutions for forced vibrations of Timoshenko
beams in a systematical manner. Damping effects on the vibrations of the beam are taken
into consideration by introducing two characteristic parameters. Laplace transform
method is applied in the present study and corresponding Green's functions are presented
explicitly for beams with various boundaries. The present solutions can be readily
reduced to those for others classical beam models by setting corresponding parameters to
zero or infinite. Numerical calculations are performed to validate the present solutions
and the effects of various important physical parameters are investigated.

Effects of Flexoelectricity and Surface in Nano-Structures
Shuling HU, Xu LIANG
State Key Laboratory for Strength and Vibration of Mechanical Structures, Xi'an
Jiaotong University, Xi’an, 710049, People’s Republic of China
slhu@mail.xjtu.edu.cn
Abstract:
Flexoelectricity and surface play essential roles in determining the electromechanical
behavior of nano scaled smart structures. Flexoelectric effect refers to the phenomenon
that strain gradient induces electric polarization in solids, which has been found in
presence of strong size-dependent electromechanical coupling response.And surface
elasticity and piezoelectricity affect the effective elastic and electromechanical coupling
coefficients. The effects of flexoelectricity and surface on electromechanical coupling
response of nano scaled structures are investigated, the modified boundary conditions due
to surface and flexoelectricity and generalized Young-Laplace equations for beam models
are derived from avariation principle. Surface elasticity plays an important role in
determining the bending rigidity of elastic beams while the residual surface stresses
influence the precise calculation of the deflection of nano beams. Surface piezoelectricity
and flexoelectricity dramatic enhanced the effective electromechanical coupling
coefficient, which impliesanew promise for energy harvester and sensors. A direct
approach for measurement of the transverse flexoelectric coefficient is also proposed.
Based on the measured electric charges and applied forces, a large flexoelectric
36
coefficient is obtained for unpoled PVDF trapezoid block. This work indicates the
potential application of flexoelectricity in NEMS and MEMS.

Crack Propagation of Single Edge Crack in Graphene Sheets under Tension
Jun HUA, Qinlong LIU
Department of Mechanical Engineering, Xi'an University of Architecture and
Technology, Xi'an, 710055, PR China
huajun211@sina.com
Abstract:
Molecular dynamics simulation is used to study the crack propagation in pre-cracked
single layer armchair graphene sheets under tension with constant strain rate. It is found
that the stress intensity factor is 123.2MPa m . The limit crack speed of grephene is 8400
m/s, while the crack speed is not a constant. The crack speed depends on the initial crack
length and the strain rate. The shorter the initial crack length, the faster the crack speed.
Higher strain load rate can improve the crack speed, but the maximum speed can’t exceed
the limit speed.

Microscopic Approach to Brittle Fracture in Complex Microstructures
Wei ZHOU
School of Mechanical & Aerospace Engineering, Nanyang Technological University, 50
Nanyang Avenue, Singapore 639798
wzhou@cantab.net
Abstract:
Catastrophic failure of structures is always a potential engineering problem. Considerable
effort has been directed towards the development of satisfactory fracture criteria to enable
engineers to design confidently against such possible failures. Fracture mechanics has
provided some basis for engineering design; however, it is a macroscopic approach and
cannot explain why some materials possess better fracture toughness than others in terms
of their microstructures and thus cannot provide a basis for developing better materials or
improving manufacturing processes. The understanding of the microscopic process of
fracture is needed to formulate local fracture criteria. The presentation will be made on
the speaker’s own researches dealing with micromechanisms of brittle fracture in a wide
range of materials, including HY steel used in the hull of British submarine, Ni-Cu
alloyed steel used in German nuclear pressure vessel, and ultrahigh strength armour steel
used in the modern infantry fighting vehicle. The focus will be placed on illustrating the
37
methodology of research rather than the experimental details. The microscopic approach
can help to understand many “unusual” fracture phenomena, e.g., why a material with
high fracture toughness KIc may be in fact very brittle and why embrittled heat-affected
zone in a welded joint could display, in contrast to common expectation, much higher
Charpy impact energy than the weld metal and parent material.

chengy@ihpc.a-star.edu.sg
Keywords: Silk fibroin; Molecular dynamics simulation; Water effect; Mechanical
property
Abstract:
Silk fibroin has attracted great attention due to its superior mechanical properties such as
ultra-high stretchability, strength, and biocompatibility. In this study, we perform
molecular dynamics simulations on β-sheet crystallite of Bombyx mori silk by pulling
out β-chains at different locations from the crystallite with/without water solvent.
Different behaviors of hydrogen bonds in vacuum and in water were examined by
carrying out long time equilibrium molecular dynamics simulation. It was found that
water greatly weakens the strength of silk fibroin. The ultimate tensile force for pulling
out a β-chain from a crystallite unit is strongly chain-location-dependent.

Keywords: Carbon Nanotubes; Spring Stiffness; Structural Stability; Nanospring;
Diffusion Behavior; Binding Stability
Abstract:
The spring stiffness and structural stability of carbon nanotube based nanospring and
nanospring have been studied. The Young’s modulus of nanoring with defects is found to
be around 282GPa, the spring stiffness is below 2.08 N/m and is nonlinear and decreases
with increasing relative elongation. The diffusion behavior and binding stability of Pt
clusters on well-aligned carbon nanotubes (WACNT) was also studied. Two main
advantages of WACNTs, which make WACNT a better catalyst (Pt) carrier, were
identified, 1) greater binding energy between Pt cluster and WACNT, 2) uniform
dispersion distribution for Pt clusters on the surface of WACNT.

Numerical Investigation of Heat Transfer in Steam Pipeline of Cargo Heating
System

Keywords: Steam Pipeline; Heat Transfer; Mixture Model; Two-Phase Flow;
Condensation
Abstract:
The heat and mass transfer of steam pipeline is investigated for cargo oil tanker, which
requires a lot of fuel to heat oil, and it is accomplished by transport of steam from boiler
to tanks. However, since pipelines are installed on deck, the steam transportion is
associated with vast energy loss, which increases fuel consumption. In order to reduce
fuel consumption, it is necessary to understand the heat loss of pipelines. A
computational fluid dynamics framework is built to simulate the two-phase flow and heat
transfer inside steam pipeline, via a mixture model for two-phase flow and a
condensation model for heat and mass transfer in phase change process. Numerical
studies are conducted to study the effects of wind speed and insulation.

Keywords: Photo-Thermal Sensitive Hydrogel; Phase Transition; Finite Element
Simulation
Abstract:
Possessing the ability to undergo large magnitudes of deformation under incremental
changes in environmental and physical stimulus, most hydrogels undergo a volumetric
phase transition in the process of undergoing large deformation. In this work, a
thermodynamic model accounting for the large deformation mechanics is presented and
applied to investigate the effects of various factors, such as chemical potential,
40
temperature, light intensity and stress, on the phase transition of the gel. In addition, a
finite element material model is developed using commercial finite element software
ABAQUS and user-defined subroutine UHYPER. The effect of light on photo-thermal
hydrogels is studied in several situations, including shrinking-induced buckling, phase
co-existence and application in microfluidic valves.

Abstract:
The kinetics deformation of temperature-sensitive hydrogel consists of polymer chains
stretching, diffuse of solvent molecule, and heat transfer process. In this study, static and
dynamic deformation theory are formulated and developed. Finite element methods are
proposed and implemented to perform static and transient analysis of deformation
process. Numerical results are compared with analytical solution and available
experimental results to verify the correctness of our approaches. They are in good
agreement. Examples are provided to investigate and illustrate the potential applications
of our methods to explain complex phenomena including bifurcation, buckling of

Abstract:
41
A probabilistic based approach is presented for the fatigue reliability assessment of a ship
structure during service life with respect to the growth of multiple site cracks. There are
multiple through thickness fatigue cracks initiated and propagated at the critical welded
joints in a stiffener-frame structure under fatigue loading. Accounting for correlated
effects caused by multiple fatigue cracks, stress intensity factors for each crack are
calculated during the process of fatigue crack propagation. The probabilistic models for
fatigue crack propagation were developed based on the Paris law. . Reliability based risk
assessment for this stiffener-frame welded structure is performed based on failure
probabilities and probabilities of detection for cracks. During the service life, the change
of the risk degree of each failure mode can be observed directly.

Keywords: Superposition Method; Data Map; Temperature Field; Printer
Abstract:
42
Finite element method (FEM) is used to simulate the temperature field in the thermal
printer. The result of FEM is in good agreement with the experimental result. However, it
is very computationally expensive. In order to reduce the time cost, superposition method
is adopted. Five representative elements are selected to represent elements at different
locations to produce data maps. In the superposition method, we just have to read the
appropriate data from the data maps and make summation. The calculation is simplified
and the efficiency is improved greatly. The result agrees well with the experimental result.

Email: yeojj@ihpc.a-star.edu.sg
Keywords: A Multiscale Approach; Molecular Dynamics; Transdermal Drug delivery
Abstract:
Topical drug application onto the skin is a common method to enhance the skin’s
characteristics. Green tea extracts, such as epigallocatechin-3-gallate (EGCG), were
reported to be extremely beneficial, having anti-oxidating and wound-healing properties.
This study aims to model the diffusion and penetration of small molecules such as cell-
penetrating proteins into the skin’s lipid bilayers. Detailed understanding of these
processes could lead to enhanced transdermal delivery of drugs which are not as
permeable, such as EGCG. Due to the extremely lengthy time- and length-scales involved,
the problem is tackled in different ways, using molecular dynamics, replica exchange,
and coarse-graining.
