Objective: Designing machines, vehicles, and structures that are safe, reliable,and economical requires both efficient use of materials and
assurance that structural failure will not occur. This courseconsiders the role of material selection in the design of mechanical
and structural elements with respect to static failure, elastic
stability, residual stresses, stress concentrations, impact, fatigue,creep, and environmental conditions on the mechanical behavior ofengineering materials (metals, polymers, ceramics, composites).
The professional and ethical responsibility of the engineer in thiscontext will be considered where appropriate.
Ultrastructural and microstructural aspects of materials are
reviewed in terms of how they influence mechanical properties.Mechanical test methods are reviewed. Models for deformation
behavior of isotropic and anisotropic materials are considered.Methods to analyze static and fatigue fracture properties are
considered. Rational approaches to materials selection for new andexisting designs of structures are examined. Failure analysis
methods of failed structures are considered. Failure analysisexamples of actual failed structures will be discussed and the
professional and ethical responsibility of the engineer will beconsidered.
Laboratories: There will be 4 mandatory laboratories. Times and locations will
be arranged as everyone will have to do the lab at the same time.Each laboratory will require at least 1 hour of preparation prior to
the lab meeting to organize procedures and expected results. FORSAFETY REASONS, STUDENT ARRIVING AT THE
LABORATORY TIME UNPREPARED OR WEARING
INAPPROPRIATE CLOTHING WILL NOT BE ALLOWED
TO OPERATE EQUIPMENT AND MAY BE DENIED
ENTRANCE TO THE LABORATORY. A report will be part
of each lab. Group Lab reports will be prepared, with differentgroup leads assigned for each lab.
Homework: Homework problems are to be worked on individually, unless
otherwise specified. Homework assignments will be givenapproximately once a week. Homework is due on the date shown
by 5PM. BECAUSE OF THE SHORT SUMMER TERM, NOLATE HOMEWORK WILL BE ACCEPTED.

Assessment: The homework assignments will be utilized to assess the students
ability to apply their knowledge of mathematics, science andengineering to solve formulate and solve problems. The
homework assignments will also be utilized to assess the studentsability to consider materials selection in the design components or
systems to meet a specific design rationale. The Laboratoryreports will be utilized to assess the students ability to design and
conduct experiments and to analyze and interpret data. LaboratoryReports will be utilized to assess the students ability to
communicate effectively in written format. The Exams will beused to assess the students ability to synthesize and appropriately
apply the concepts concerning materials selection and deformation,fracture and fatigue of materials learned in class.
