Large Deformation Simulation of Pressure Sensitive AdhesivesPartII: Constitutive Equation for Pressure Sensitive Adhesive

Abstract

A constitutive equation of pressure sensitive adhesives is described. The material characteristics of pressure sensitive adhesives indicate viscoelasticity and rubber-elasticity. The effective large deformation simulation of pressure sensitive adhesives should be inquantitative consistency with practical behavior. For the quantitative consistent simulation, the constitutive equation including every material characteristicis indispensable. This paper proposes the constitutive equation for pressure sensitive adhesives, which covers viscoelasticity and rubber-elasticity, and tests the validity of the proposed constitutive equation by using comparison with experiment and computational results.
