## Problem Specification

Consider the square plate of uniform thickness with a circular hole with dimensions shown in the figure below. The plate is uniaxially loaded with a uniform pressure *p*=1 MPa. In addition, the plate is made of a Glass/Epoxy composite material with the fibers oriented in same direction as the applied load. The material properties are as follows:

Young's modulus in the fiber direction Ex = 59.3 GPa

Young's modulus in the transverse direction Ey = 22 GPa

In-plane shear modulus Gxy = 8.96 GPa

Major Poisson's ratio n_{xy} = 0.26

Minor Poisson's ratio n_{yx}= 0.047

The circumferential stress concentration on the boundary of the hole is to be determined using ANSYS.
