WebDefining strain-rate-dependent material behavior for elastomers The elasticity of the model is defined by a hyperelastic material model. You input the stress scaling factor and the creep parameters for network B directly when you define the hysteresis material model. WebHookes law tells us that the stress is proportional to strain but you can only use this within the elastic limit so the natural question now is what happens when we go beyond the elastic limit I mean we know the proportionality won't work anymore but what happens to the material and that's what we're going to explore in this video and so before … dr michael hickman metairie
