Buckling of laminated skew plates

TLDR: In this paper, a high precision triangular plate bending finite element has been extended to the buckling analysis of laminated skew plates, which involves development of the transformation matrix between global and local degrees of freedom for nodes lying on skew edges and suitable transformation of the element matrices.

Abstract: A general high precision triangular plate bending finite element has been extended to the buckling analysis of laminated skew plates. This procedure involves development of the transformation matrix between global and local degrees of freedom for nodes lying on the skew edges and suitable transformation of the element matrices. The accuracy of the present formulation has been verified against literature values. New results are obtained for antisymmetric angle-ply and cross-ply laminated skew plates. In this analysis, the critical buckling loads for different skew angles with various lamination parameters, such as number of layers, fibre orientation angle, different boundary (simply supported, clamped) and loading (uniaxial, biaxial) conditions, have been presented.
