Abstract

In this study, an analytical solution procedure for elastic-plastic stress analysis of laminated beams is presented. The Bernoulli-Euler theory was used in the solution considering infinitesimal small deformations. A finite element analysis was also carried out, by using LUSAS 13.4, to compare and verify results obtained by analytical solution. Several stacking sequences such as [0 degrees/90 degrees]s, [90 degrees/0 degrees]s, [15 degrees/-15 degrees]s, [30 degrees/-30 degrees]s, and [45 degrees/-45 degrees]s are chosen for comparison.
