The objective of this video is to explain Von Mises yield criterion followed by a brief comparison of Von Mises’ and Tresca’s yield criterion. 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.

Course Description
This course builds on the concept of force and moment equilibrium learnt from first year engineering mechanic and physics courses and focuses on the internal actions and deformations experienced by simple structural members under loading. Concepts learnt in the course such as load transfer through axial, shear, bending and torsion as well as stress and strain relationships are the foundation for further study in any structural engineering related courses.
