Abstract

A compressible version of the nonisothermal Leonov-model is proposed to describe the viscoelastic behaviour of a polymer melt. Elaborating it to an incremental formulation of the balances of momentum and energy it can subsequently be implemented in a thermomechanically coupled finite element code. An Arbitrary Lagrange-Euler method is used, being particularly suitable for history dependent processes involving free surface movements. Occurring numerical problems are discussed and some isothermal results are presented.
