Theories of FailureThe Maximum -Shear -Stress TheoryThe Maximum Shear Stress theory states that failure occurs when the maximum shear stress from a combination of principal stresses equals or exceeds the value obtained for the shear stress at yielding in the uniaxial tensile test.At yielding, in an uni-axial test, the principal stresses are V 1 = S y ; V 2 = 0 and V 3 = 0.Therefore the shear Failure Theories.

Stress theories of failure

Note that the Out-of-Plane Principal Stress (s III) for the strain plane condition is zero; Failure occurs when the maximum of the Three Maximum Shear Stresses reaches the shear yield stress, t Y. The above plot is a Failure Map. If the In-plane Principal Stresses lie outside the shaded zone, failure occurs. Theories of failure - View presentation slides online.

The plies with higher strength ratios will fail later, when the externally applied load is increased. This successive ply failure progresses until the last ply or ultimate failure occurs.

Factor of safety for each failure theories : i) Maximum Normal Stress Theory: ( Theory states that failure occurs if any of the principal stresses exceeds the yield   In this article, we will discuss two of the common failure theories for ductile materials: the max. shear stress and max. distortion energy theories.

In simple terms, the formula says that failure occurs when the principal stress reaches the yield stress. von-Mises failure criterion (maximum distortion-energy theory) The MAXIMUM NORMAL STRESS FAILURE THEORY states that when the Maximum Normal Stress in any direction of a Brittle material reaches the Strength of the material - the material fails. Thus, finding the Principal Stresses at critical locations is important. Mathematically failure occurs when: SU is the ultimate strength in Tension Theories of failure Introduction Theories of failure are those theories which help us to determine the safe dimensions of a machine component when it is subjected to combined stresses due to various loads acting on it during its functionality.
