Abstract:

A description of nonlinear one dimensional viscoelastic material behavior is given in terms of models which incorporate a combination of strain hardening and age hardening techniques for generalizing creep laws to viscoelastic constitutive equations. After some discussion of the behavior of these models under various loadings, the problem of wave propagation down a suddenly loaded semi-infinite rod of material described by one of these nonlinear constitutive equations is solved by numerical integration along the characteristics of the problem. A linear instantaneous elastic response is assumed in all cases. Author
