The difference in the ratios is related to the spread of the cross-sectional areas of the test pieces used in the computation of the moduli of elasticity. An indirect method of estimating the Poissonâs ratios can be based on the axial moduli of elasticity, E x and E y, and the panel shear modulus of elasticity, G xy, of the test
