WebVon Mises’s stress concept is developed from the distortion energy theory and a highly preferred failure theory used in the mechanical design industry. This theory is devised … WebVon Mises Failure Criterion. The general strain energy density function in terms of stresses and strains, applies for all materials (timber, concrete, steel, rubber, etc.) However, for any cube in space, you can find the orientation (pitch, yaw) that has only principal stresses, i.e. no shear stresses. In this unique orientation, the strain ...
