Question

12-10. A metal bar is being compressed along the x,-axis between two rigid walls such that e3 = 0 and σ2, = 0. This process causes an axial stress σ1 and no shear
stresses. Determine the apparent yield value of σ1, if the material in a conventional compression test exhibits a yield strength σyp and Poisson's ratio v. Assume that the material is governed by the von Mises yield condition. Find an alternative expression if the Tresca condition is postulated.
