Theories of failure are those theories which help us to determine the safe dimensions of Maximum Principal Stress theory also known as RANKINE'S THEORY.

Theories of Failure. Failure of a member is defined as one of two conditions. 1. Fracture of the material of which the member is made. This type of failure is the. Fracture and Failure Theory. Defining Failure. Failure can be defined in a variety of ways: Unable to perform the to a given criteria; Fracture; Yielding . Theories of Failure. Strength of a material or failure of the material is deduced generally from uni-axial tests from which stress strain characteristics of the material.

theories of failure are being suggested by different people: (i) Rankine's theory or maximum normal stress theory. (ii) Guest's theory or maximum shear stress. Maximum Principle Stress Theory  This theory is suitable for the safe design of machine component made up of brittle material, because brittle material are weak in tension  This theory is not good for design of ductile material because shear failure may occur  But this theory is also suitable for ductile material.
