Given: a Blatz–Ko material with μ = 100. Consider a tensile test of a cube of side length 1 unit, subjected to a force of 40 units normal to the edges x = constant.

(a) Use ANSYS to determine the stretches and the true stress (see Section 15.22). Note that you only need one element since the displacements are uniform over the element. Use the Solid 185 element. Use t =1 and a step size of 0.1.

(b) Compare the solution by ANSYS to the exact formula.
