Abstract
Viscoelastic polymer foams (soft foams) as well as synthetic sponges are of great interest in various fields of engineering. As a result of the foaming process, these materials exhibit an open or closed cellular micro structure leading to a macroscopic porosity of more than 90 %. Following this, extremely large deformations can occur giving these materials their outstanding mechanical characteristics.
The goal of this paper is to present an efficient macroscopic continuum mechanical model based on the Theory of Porous Media (TPM) in order to carry out numerical investigations at suitable means of computational costs. In particular, the model accounts for the complex cellular structure including the intrinsic viscoelastic behavior of the polymeric skeleton which is saturated by an independent compressible pore-gas constituent.
