Abstract
This paper presents a temperature-dependent visco-hyperelastic analysis scheme for pressure-sensitive adhesive with an Eulerian finite element method. All the basic equations are numerically solved in the Eulerian framework because it allows arbitrarily large deformations. Visco-hyperelasticity is formulated using Simo’s finite-strain viscoelastic model, where hyperelasticity is modeled as a strain energy function based on Yamashita-Kawabata model. The left Cauchy-Green deformation tensor is temporally updated from the Eulerian velocity field without material points. Temperature-dependence is described with the time-temperature superposition principle of Williams, Landel, and Ferry. To validate the proposed approach, we simulate uniaxial tension tests under different tensile speed and temperature conditions.
