Cowper Symonds Piecewize Linear Hardening, strain rate dependent

      In WB LS-Dyna, how to use keyword snippet in to define many stress strain curves for different strain rates for Coper Symonds Hardening? I think this is suppored in Engineer data, right?

      Thanks

      Hello,

      You don't need a command snippet (at least with WB 2022R2). To use different stress-strain curves for different strain rates  with *MAT_024 (*MAT_PIECEWISE_LINEAR_PLASTICITY), you can go to engineering data and do the following (see image below). With this method, no need to specify Cowper and Symonds parameters:
