Abstract

The aim of current work is to investigate the tensioned composite plates with two types
of cutouts. Many industrial applications use composite matrix with reinforcement fiber to
obtain better properties. The objective of this work is divided into two parts, first the
experimental 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 different
number of layers and types of cutouts of composite materials by using strain gages technique
under constant tensile loads to compare with the numerical results. The second part is
numerical work, which involves studying the static analysis of symmetric square plates with
different types of cutout (circular – square). In static analysis, the effect of the following
design parameters on the maximum stress (σx), strain (εx) and deflection (Ux) is studied. This
part of investigation was achieved by using the software finite element
package (ANSYS 5.4).
