Abstract

In this study, analysis of residual stress and deformation in CFRP which is anisotropic thermoviscoelasticity is discussed. The analysis is calculated, according to thermoviscoelastic theory which is based on time-temperature superposition, and using Laplace transformation for 2-dimensional and 3-dimensional BEM. Thermoviscoelastic model is approximated by Maxwell model.
