New Material Model for Describing Large Deformation of Pressure Sensitive Adhesive

A material model to describe large deformation of pressure sensitive adhesive (PSA) is presented. A relationship between stress and strain of PSA includes viscoelasticity and rubber-elasticity. Therefore, we propose the material model for describing viscoelasticity and rubber-elasticity and formulate the presented material model for finite element analysis. And we validate the present formulation by using one axis tensile calculation.
