Thermoviscoelastic Analysis of Three-Dimensional Orthotropic Solid Polymers Using a General Finite Element Formulation

The objective of this study is to develop a general finite element formulation associated with an incremental adaptive procedure which established for analysis of the orthotropic thermoviscoelastic materials. This paper concerned with development of a numerical algorithm for the solution of the quasistatic initial/boundary value problems involving the linear viscoelastic media with thermal and mechanical deformations. The viscoelastic constitutive equations, represented in an integral form and involving relaxation functions, are transformed into an incremental algebraic relation. An incremental relaxation is then developed for the finite element formulation to deal with quasistatic thermoviscoelastic problems.
