WebFailure boundaries and Mohr's circle DUCTILE MATERIAL One theory that is used for the prediction of failure in a ductile material is the maximum shear stress theory (MSS). The basis of this theory is that failure will occur when the maximum shear stress exceeds the maximum shear stress that exists for yielding in a uni-axial test. Consequences: WebA. K. Sengupta MET 301: 3D stress 1/3 1-21 Stress in three dimensions In three dimensions, in each orthogonal direction X, Y & Z, there could be one normal and two shear stresses. Thus the most generalized state stress at a point in 3D is as shown below. It is also conveniently described by a stress tensor as follows: Stress Tensor =
