UNITS IN ABAQUS

Before starting to define any model, you need to decide which

system of units you will use. ABAQUS has no built-in system of

units.

Length m mm

Force N N

Mass kg tonne (103kg)

Time s s

Stress Pa (N/m2) MPa (N/mm2)

Energy J mJ (103J)

Density kg/m3 tonne/mm3

Creating Part

1. Start ABAQUS/CAE

2. Create Model Databasefrom the Start Session

3. In the Module Tool, click theParts

4. Name the partFrame.

5. Choose : modeling space ( 2D planar or 3D ),type( deformable, discrete or Analytical rigid ),

Base Feature ( Shell, wire or point).

6. In the Approximate sizetext field.

7. Click continue.

Creating Part

1. SelectRectangletool to draw a rectangle2. Use the Add Constraint tool to constrain the top and

bottom edges

3. Use the Add Dimension tool to dimension the edges of

the rectangle

4. Use the Connectedtool to start draw lines.5. Use the Splittool to split either of the two interior lines

as the second entity and so on.

Creating a material

To define a material:

1. In the Model Tree, Click the Materialscontainer

to create a new material

2. Name the material

3. In the menu bar, chooseMechanicalElasticityElastic

4. Type a value for Young's modulus and a value for

Poisson's ratio in the respective fields

5. Click OK.



18/30

Defining and assigning section properties

The section properties of a model is defined by creating

sections in the Property module

To define a truss section

1. Choosing Sectionsto create a section.

2. Name the sectionABC > select in the Categorylist

>select in the Typelist

3. select name Material in edit section.

4. In the Cross-sectional areafield

To assign the section to the frame:

1. Under Parts,expand the Frameitem

2. Click Section Assignments > highlights theentire frame >click Donein the prompt area

to assign the frame to section.



19/30

Defining the assembly

Define the geometry of the assembly by creating

instances of a part and then positioning the instances

relative to each other in a global coordinate system .

To define the assembly:

1. Click Assemblyunder the Module list >Click Instances

2. Choose: independent or dependent

3. Using Auto-offset ( > 2 part)

4. Click Apply.



20/30

Creating analysis steps

Click create step > choose step name

1. Select a procedure type

2.Click continue.

3. Select basic ( setting time period) > select

incremention (choose maximum numberincrement> increment size)



21/30


Once you create a step, ABAQUS/CAE generates a default

output request for the step.
