Effect of Thickness on Interlaminar Stresses in Simply Supported FRP Cross-Ply Laminates with a Circular Cutout

摘要

The present research work deals with the prediction of interlaminar stresses in simply supported laminated FRP composite plate with a circular cut-out under transverse load using 3-D finite element analysis. The finite element analysis software ANSYS has been successfully executed and the finite element model is validated. The interlaminar stresses are evaluated by varying length-to-thickness ratio (s) and constraints. The effect of 's' and the boundary conditions on the interlaminar stresses is discussed. The present analysis will be useful in quantifying the effect of above said factors that helps in the safe and efficient design of the structural elements made of laminated FRP composites.
