摘要：The static response of simply supported carbon/epoxy composite plates in a hygrothermal environment is carried out using the general purpose finite element program COSMOS. The static load model and the hygrothermal incorporation are solved separately. The hygrothermal effect is introduced by using empirical relations for degrading the material stiffness properties of the matrix. The corresponding ply properties are calculated using Mori-Tanaka method. A parametric study is conducted by varying the fiber volume fraction and the fiber orientation of the angle plies in the laminate.
