Abstract

This study deals with elastic-plastic behavior of aluminum metal-matrix laminated cantilever beam subjected to a bending moment at the free end. The Bernoulli-Euler theory is utilized in the solution and small plastic deformations are considered. The beam consists of four layers and its material is assumed to be linearly hardening. A few ply arrangements such as [90°/0°]s, [30°/-30°]s, [45°/-45°]s and [60°/-60°]s are taken into consideration for such an analysis. The moment values that initiate plastic flow at any point of the beam are carried out for diverse stacking sequences. The variation of the elastic, elastic-plastic and residual stress components versus increasing plastic zone spread are given in tables and figures.
