Abstract

The time-dependent response of polymeric matrix laminated composites subject to mechanical and hygrothermal loads is considered. The analysis is based on an incremental total Lagrangian formulation which allows the treatment of finite displacements and small strains. A three-dimensional degenerated finite element model is employed to analyze the plates and shells. The material is considered as linear viscoelastic and hygrothermal-rheologially simple. Numerical examples for isotropic and graphite-epoxy laminated plates and shells are presented.
