How to include a non-linear material model ?
Altair EmployeeI have the stress - strain values at discrete data points from uni- tensile test. How too include that in Hypermesh while defining material properties ?

Next, populate the X and Y fields of the table, as shown below.
7.
Click Apply.
A dialog box will appear which says 'The load collector with TABLES1 card image is created’.

Click OK to close the dialog box.
Now, the elasto-plastic material needs to be updated.

Please also tell how can we add temperature dependent specific heat values. The above process is for stress strain curve but following same procedure in specific heat or thermal conductivity I am not able to assign the values. I am using optistruct in Hyperworks 12.

Hi Ahilan,
The stress-strain curve should be defined using TABLES1 card and MATS1 cards.
