STUDYING THE EFFECT OF CUTOUTS ON THE COMPOSITE LAMINATE PLATES

Abstract

The aim of current work is to investigate the tensioned composite plates with two typesof cutouts. Many industrial applications use composite matrix with reinforcement fiber toobtain better properties. The objective of this work is divided into two parts, first theexperimental work covers the measuring of the normal strain (εx) at the edges of (circular &square) holes that are perpendicular to the direction of the applied loads with differentnumber of layers and types of cutouts of composite materials by using strain gages techniqueunder constant tensile loads to compare with the numerical results. The second part isnumerical work, which involves studying the static analysis of symmetric square plates withdifferent types of cutout (circular – square). In static analysis, the effect of the followingdesign parameters on the maximum stress (σx), strain (εx) and deflection (Ux) is studied. Thispart of investigation was achieved by using the software finite elementpackage (ANSYS 5.4).
