【 摘 要 】

One of the factors influencing the stiffness and stresses of the plate is skew angle of the plate. The present work focused on evaluation of the effect of skew angle on geometric nonlinear behavior of a four layered symmetric cross-ply (0°/90°/90°/0°) skew laminated fiber reinforced plastic (FRP) composite plate with a circular cutout at the geometric centre of the plate. The problem was modeled in ANSYS software and was executed for satisfactory results by performing convergence of the finite element mesh. Results were obtained for a uniform transverse pressure of 0.5 MPa for four different skew angles of the plate. The limitations of the linear assumption and the need for nonlinear analyses are stated.
