What are the two types of deterministic failure methods and which type is applied to which type of material?

Solution

The two types of deterministic failure methods are

1) Maximum principal stress failure

2) Maximum shear stress failure

Maximum principal stress failure is used in case of brittle materials mostly such as high carbon steels

Maximum shear stress failure is used in case of ductile materials only such as aluminium and low carbon steels.
