Von Mises’ criterion is based on the energy associated with the distorted shape of an element. The yielding is assumed to occur when the shearing distortion of an element under a combined stress state is equal to shearing distortion energy of uniaxial tension yield. Moving on, the video expresses the Von Mises yielding criterion in terms of three dimensions using the principle stresses explaining all the facts in details. • The video, then, represents Von Mises yield criterion as geometric interpretation of ellipse showing that how yielding takes place outside the ellipse and no yielding within the ellipse. Later, the video does a brief comparison of Von Mises’ and Tresca’s yield criterion over a graphical representation concludes the fact both yield surfaces do not differ significantly. In addition, geometrically both the criterion gives better combined yield stress calculation.
