A sheet of copper is stretched biaxially in the xy-plane. If the strains in the sheet are 0.40 x 10 -3 in the
x direction and 0.30 x 10-3 in the y direction, determine the stresses in the x and y direction. Also,
determine the strain in the z direction. The modulus of elastic and Poisson’s ratio of copper is 110
GPa and 0.35 respectively.
