A plate with epoxy reinforced with unidirectional glass fibers has the following elastic constants: E_{xx}=70GPa, E_{yy}=5.0GPa, G_{xy}=1.5GPa, u_{xy}=0.24, and G_{yz} is approximately 10% less than G_{xy}. Stresses of \sigma_{yy}=20MPa, \sigma_{xx}=70MPa, and \tau_{xy}=8MPa are applied to the composite plate. Determine the values of \epsilon_{xx}, \epsilon _{yy}, \epsilon_{zz} and \gamma_{xy}. (Hint: use matrix symmetry and material symmetry to address the missing elastic constants)
