Theory of failure. Which one is used widely and why

Question

Accepted Answer

The theory of failure widely used in engineering is the Von Mises criterion due to its accuracy in predicting material failure under complex loading conditions.

Von Mises criterion is widely used in engineering for predicting material failure under complex loading conditions
It takes into account both normal and shear stresses to determine the equivalent stress that leads to failure
Other theories like Maximum Principal Stress theory and Maximum Shear Stress theory are less accurate for complex loading situations
Von Mises criterion is commonly used in designing structures, machines, and components
