FEM analysis of buckling and thermal buckling of antisymmetric angle-ply laminates according to transverse shear and normal deformable high order displacement theory. (English) Zbl 0726.73073

Summary: Buckling and thermal buckling of the antisymmetric angle-ply laminates clamped and subject to in-plane edge loads or a uniform temperature rise are analyzed by the finite element method. A higher order displacement theory including higher order terms along the transverse direction, taking into account transverse normal strain, is applied through the analysis. Effects of important parameters, such as ply angle, ratio of thickness to edge length, number of layers, ratio of in-plane to transverse modulus, etc. are studied. The numerical results are presented.
