Question

A bar of elastic material subjected to a compressive stress σx in an axial direction and its strains at right angles are reduced to half to those which normally would occur in an ordinary tension member. If E = 208 kN/mm2 and v = 0.3, what is modified modulus of elasticity in x-direction.

Answer 1

Note that all the stresses in x-, y- and z-directions will be negative, i.e.,
