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 … WebThe Von Mises criteria is a formula for combining the three principal stresses into an equivalent stress, and the equivalent stress is then compared to the yield stress of the material to judge the failure condition of the material. The equivalent stress is often called the Von Mises Stress, as a shorthand description.
