Abstract (EN): A new p-version finite element based on a zig-zag layerwise theory is developed. With the proposed model, one can accurately determine the behaviour of laminated composites with different material properties, straight or curvilinear fibres. Comparative studies with published results and with results from finite element software Abaqus are performed to verify the new model. Deflections in the linear and non-linear regimes are then calculated for several constant and variable stiffness composite laminates (VSCL), in which the fibre orientation angle varies linearly in each layer. In a few cases, VSCL plates show better performance in comparison to CSCL plates both in the linear and non-linear regimes. It is also found that it is possible to take advantage of VSCL by varying fibre orientations only in some plies of a laminate, hence reducing manufacturing costs, as well as the amount of gaps and overlaps.
