      Hello,

      I have prony shear relaxation data in the form of shear relaxation modulus and respective relaxation time constant. I am trying to apply this property to simulate stress relaxation using ls dyna integrated in ansys workbench.  Inside ls dyna material category I only found " MAT_GENERAL_VISCOELASTIC" but it requires both shear and bulk relaxation data . Since I only have shear relaxation data I believe I need to use different material card like "MAT_006" but this is not available directly in the GUI. So I want to learn how to define this material using code. Can someone guide me on this please.

      Hi, 

      You can define Material models, which are not directly supported through the GUI, using Command snippets scoped to a specific part. Remember that all load curves and tables have to be defined at the system level as follows 

      For load curves and tables defined as follows 

      You can define unsupported cards this way or use keyword manager 

      Chers, Ram
