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. !Composite_probspec.jpg!
