I'm trying to define a material with the following stress strain relationship:
stress = c1 * strain + c2 * strain2 + c3 * strain3 + c4 * strain4
Where c1, c2, c3, c4 are all constants.
Is there any way to do this in ANSYS Mechanical APDL?
you can use the results by ANSYS then you use excel program to determine the relation between stress and strain

Hi Kadhim, I know what the stress strain relationship is (I have several different values for each constant based on different test specimens), my problem is how to define this relationship in ANSYS
Hi samir ,
There is a simple method , you can applied load (by ANSYS)and caculate the stress and strain , then chang the applied load and calculate the stress -strain again , repeated this method to obtain more point (strain ,stress)
