Abstract

Nonlinear bending analysis of antisymmetric angle-ply laminates subject to a uniform temperature rise are analyzed by finite element method. A higher order displacement theory including higher order terms along transverse direction taking into account transverse normal strain is adopted through the analysis. Comparisons to the special case with Mindlin type first-order displacement field are made under various temperatures to justify the necessity of using the higher order displacement field. Effects of important parameters, such as ratio of thermal expansion coefficients, number of layers, ratio of Young's moduli, etc., are also studied. Numerical results are presented.
