Abstract

The present work deals with second order statistics of buckling strength and first-ply failure by load of laminated composite plate subjected to compressive loading with random system properties and strength parameters. The mathematical formulation is based on higher order shear deformation theory (HSDT). An efficient C 0 linear finite element method procedure in conjunction with a second order perturbation approach (SOPT) is developed and applied for failure problem in random environment using Tsai-Wu failure criterion. It is observed that the random system properties and strength parameters have a significant influence on the linear first-ply failure load and buckling response of composite plate. The results obtained using present solution approach is validated with the results available in the literatures.
