Dear Behrouz,

For more detailed analysis you can define your material model and properties in UMAT subroutine.

Hi Behrouz,

In the model tree you will find "Materials". Double click on that to open the create material dialogue box.

Select Mechanical- Elasticity- Elastic and add the required elastic properties. Similarly add the plastic properties

Then from the main menu in materials module go to Section>Create>Name the section and select the type of structure and material distribution type>Continue>Select the material created>OK

To assign the material lastly go to Assign>Section>Select the part to which the new material is to be assigned>Select the named section from the list>OK

Your material will be successfully defined and assigned as well.

Thanks
