Three dimensional exact solution of thermal stresses in rectangular composite laminate

Three-dimensional exact solutions for temperature distribution and thermal stresses in simply supported finite rectangular orthotropic laminate subjected to prescribed boundary conditions under combined thermal and mechanical loading, are presented which will be used to check the accuracy of more generalized numerical tools. The numerical results are presented for across-ply 3-layered 0/90/0. composite laminate. The numerical results help to draw the conclusion that the influence of the thermal field on deformations and stress is very predominant and induces high transverse normal stress at the interfaces which may cause the failure of the weak interlayer adhesive bond.
