Abstract

Coupling responses in laminated panels complicate theoretical analysis and render closed form solution virtually impossible. The assumption that coupling can be ignored (especially orthotropic case) simplifies the analysis, but unconservative results are obvious, especially for laminates with a small number of layers. In this paper, the flexibility of the finite strip method is presented for the analysis of laminated composites in compression. Coupling responses in laminates are taken into consideration in the analysis via the use of the “reduced bending stiffness” concept. Parametric study of laminates subjected to various loading and boundary conditions are presented and discussed.
