The shear modulus, G ₁₂ , of a lamina or unidirectional laminate can be obtained from a cross beam test or a rail shear test, both of which endeavor to provide conditions of uniform shear. However, the shear modulus may be simply determined from a uniaxial tension test of a [?45] _Ns laminate. By considering such a laminate, show that:

where E _x and v _xy are Young's modulus and Poisson's ratio of the laminate. Is this a quasi-isotropic laminate?
