A block of isotropic material is stressed in the x- and y-directions, but rigid walls prevent deformation in the z-direction, as shown in Fig. P5.25. The ratio of the two applied stresses is a constant, so that σy = λσx.
(a) Does a stress develop in the z-direction? If so, obtain an equation for σz as a function of σx, λ , and the elastic constant ν for the material.
(b) Determine the stiffness E’ = σx/εx for the x-direction as a function of only λ and the elastic constants E and ν for the material.
(c) Compare this apparent modulus E’ with the elastic modulus E as obtained from a uniaxial test. (Suggestion: Assume that ν = 0.3 and consider λ values of −1, 0, and 1.)
