Nonlinear finite element analysis requires the derivation of the secant elastic stiffness matrix of the discretised mechanical system. Most approaches of the literature lead to express the secant stiffness matrix as an asymmetric matrix, which then c

Analytical calculations were performed on carbon fiber-reinforced polymer (CFRP) laminates in an asymmetrical configuration. The asymmetric configuration of composites was investigated, where extension–twisting and extension–bending couplings wer

A set of carbon-fibre laminated specimens have been subjected to (static) four-point bending tests to assess the conditions for delamination induced by local buckling events of the compressed lamina. Testing conditions prescribed by the ASTM D7264/D7

Extended higher-order sandwich plate theory is used to analyze the free vibrations of rectangular sandwich plates with compressible core. Accordingly, first-order shear deformation theory is used to model the laminated face sheets. Besides, the in-pl
