I would like to input  non-linear materials (Stress-strain curve) in radios server.

Please answer me.

1. what is materials type ? If materials is plastics.

2. How to input materials ?

    Hi,

     

    Check LAW 60.' This law models an isotropic elasto-plastic material using user-defined functions for the work-hardening portion of the stress-strain curve (i.e. plastic strain vs. stress) for different strain rates. It is similar to Law 36, except yield stress is a nonlinear interpolation from the functions. '

     

    You can use funtion options to input material properties.
