Stress Strain Material table

Hi,

 

I have a question concerning the material definition in Hypermesh using the Radioss solver. Is it somehow possible to define the material with the aid of experimental material data (from a tensile test)? I want to simulate an elasto-plastic modell but I don't know how to input the real stress-strain values.

 

Thanks for your help!

    Hi Marius89,

     

    If you have a elasto plastic isotropic material you can use MAT/LAW2 to enter the stressVsStrain data.

     

    Please refer to the RADIOSS user guide for more information.

    Hi,

     

    Please refer /MAT/LAW36 (PLAS_TAB) is Isotropic elasto-plastic material using user-defined functions for the work-hardening portion of the stress-strain curve.
