An analytical solution procedure to analyze material nonlinear behavior of laminated beams

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°/90°]S, [90°/0°]S, [15°/-15°] S, [30°/-30°]S, and [45°/-45°]S are chosen for comparison. © 2007 SAGE Publictions.
