Abstract [en]

Following the growing use of amorphous polymers in an expanding range of applications, interest for polymer mechanical modeling has greatly increased. Together with reliable constitutive models, stable, accurate and rapid integration algorithms valid for large deformations need to be developed. Here, in a framework of hyperelasto-viscoplasticity and multiplicative split formulation, three integration algorithms (explicit, fully implicit and forward gradient) are applied to the polymer model developed by Anand and Gurtin (2003) and respective stability is investigated. The explicit and fully implicit algorithms were furthermore implemented in a commercial Finite Element code and simulations of a simple tensile test are shown to capture the actual deformation behavior of polymers.
