THERMO-VISCOELASTIC PERFORMANCE OF A LIQUID METAL POLYMER COMPOSITE
Resumo
In contrast to elastic problems where history can be ignored, viscoelastic materials require a knowledge of the entire history that the material has experienced. In many papers the viscoelastic properties have been entered into commercial FEM systems and the time history been obtained. In this paper we make use of an iterative process involving a Lagrangian approach based upon the matching of a second order Piola-Kirchoff and Cauchy analyses of the current spatial description of the system using Schapery material model. Excellent results are obtained.
