A material is tested under the proportionally increasing state of stress, with the stress ratios of: 01 =202 = -303. Yielding is observed at 03 = - 200 MPa. a) If the material yields according to the Von Mises yield criterion, what would be the yield stress of this material under simple tensile loading? b) If the same material is used under the conditions such that 01 = 302 = -203, at what values of 03 will yielding occur?
