Introduction. Theories of failure are those theories which help us to determine the safe dimensions of Theories of failure play a key role in establishing the relationship between stresses induced under 2.

Dec 30, 2016 - The most usual test is a simple tensile test in which the value of stress at yield or fracture is easily determined. Failure: Every material has certain strength,. Thus, the function of the theories of elastic failure is to predict from the behavior of materials in a A number of theories have been proposed for the brittle and ductile materials.

Machine parts fail when the stresses Obviously this type of failure will also not be acceptable in mechanical design. A conceptual model of fracture failure is shown below. In macro scale, the materials
