WebFailure Theories for Ductile Materials. In this article, we will discuss two of the common failure theories for ductile materials: the maximum shear stress theory and the maximum distortion energy theory. We'll also discuss why the maximum normal stress theory should never be used with ductile materials. When we have a situation with combined ... WebMaximum Distortion Energy Criterion or von Mises' Yield Criterion (Blue Regoin is Safe) The third theory looks at the total energy at failure and compares that with the total energy in a unixial test at failure. Any elastic member under load acts like a spring and stores energy. This is commonly called distortational energy and can be calculated as sheraton framingham restaurant
