Polymer matrix composite laminate under hygrothermal exposure

The static load model of laminate with the hygrothermal load is considered in the paper. The corresponding ply properties are calculated using Mori-Tanaka method. A parametric study is conducted by varying the fiber volume fraction in one laminate layer and the fiber orientation of the angle plies in the laminate. The internal forces of laminate plate with symmetric and unsymmetric stacking of layers are investigated.
