Abstract

A phenomenologically motivated small strain model to simulate the curing of thermosets has been developed and discussed in a recently published paper (Hossain et al. in Comput Mech 43(6):769–779, 2009). Inspired by the concepts used there, this follow-up contribution presents an extension towards th...
