Abstract
In this work, thermal residual stress in CFRP laminates is analyzed using two-scale analysis method based on a homogenization theory for thermoelastoviscoplasticity. For this purpose, the homogenization theory for thermoelastoviscoplasticity is constructed by introducing the effect of thermal expansion into the homogenization theory for time-dependent materials. Then, using this theory, two-scale analysis method is established. This method is applied to the analysis of thermal residual stress in CFRP laminates which have three types of laminate configurations, i.e. unidirectional, symmetrical cross-ply, unsymmetrical cross-ply. The effect of the laminate configurations on the thermal residual stress are investigated.
