Theories of failure for brittle materials (part-3): Maximum principal stress theory

Maximum principal stress theory is useful for brittle materials. Maximum principal stress theory or maximum principal stress criterion states that failure will occur when maximum principal stress developed in a body exceeds uniaxial ultimate tensile/compressive strength (or yield strength) of the material. Maximum principal stress theory/criterion is also known as normal stress theory, coulomb or …
