Hello,

 

Mathe card has no option for defining density. So how does it takes into account mass of model?  Also what about modal ,transient and frequency analysis where inertia is important factor? 

 

Regards

Bharat

    MATHE is Non linear Hyperelastic material.Hence used for Nonlinear analysis only.

    Hello Rahul,

    Thank you for the reply.

     

    If I want to perform a frequency response analysis of Rubber material, then what is the option?

    Preloading with nonlinear material for buckling is available from 14.210 solvers patch.For FRF i am not sure but it would be available in future version.See attached screenshot.
