TL;DR: In this article, a variational approach for stress analysis in a general symmetric laminate, having a uniform distribution of ply cracks in a single orientation, subject to general in-plane loading is presented.

TL;DR: In this paper, an admissible stress field has been used in conjunction with the principle of minimum complementary energy to get the effective stiffness matrix of a cracked general symmetric laminate.

TL;DR: In this paper, an exact methodology is developed based on Levin's theorem to evaluate the effective thermal expansion coefficients of cracked laminates, and an admissible stress field, which satisfies equilibrium equations and all the boundary and continuity conditions, has been considered in conjunction with the principle of minimum complementary energy and a ply refinement technique in order to exactly predict degradation of all thermo-elastic constants of cracked symmetric Laminates.

TL;DR: In this paper, a variational model is developed to exactly determine both stress and displacement fields at free edges of general symmetric composite laminate strips under thermomechanical loads.

TL;DR: In this article, a variational model is developed for predicting stress transfer due to ply cracking in general cross-ply laminates subject to out-of-plane bending and biaxial in-plane loading.
