Parameter Estimation of Viscoplastic Polymers

Application ID: 117671

This tutorial model demonstrates how to estimate the material parameters of a viscoplastic Bergstrom–Boyce model suitable for nonequilibrium modeling of rubber-like materials. The data used for parameter estimation consists of cyclic uniaxial tension and compression tests at two different strain rates. After estimating the primary model parameters, the model formulation is extended to also include temperature dependence using additional data from tension experiments at different temperatures.

This model example illustrates applications of this type that would nominally be built using the following products:
