Maximum Principal Strain Theory Saint Venant's Theory Principal Strain Theory Machine
Maximum Principal Strain Theory. This theory states that the failure or yielding occurs at a point in a member when the maximum principal ( or normal ) strain in a bi-axial stress system reaches the limiting value of strain which means strain at the yield point as determined from a simple tensile test.

1. Maximum normal stress theory: This theory states that failure occurs when the maximum normal stress in a material exceeds its ultimate tensile strength (UTS). The UTS is the maximum stress a material can withstand before it fails. This theory is applicable to brittle materials such as ceramics and glass. 2.

Maximum principal strain theory. Maximum principal (or normal) strain theory is also known as Saint Venant theory. Failure occurs at a point in a machine member when the maximum principal strain in a bi-axial stress system reaches the limiting value of strain in a simple tension test. Limiting strain means the yield point of the material.

The maximum-principal-stress criterion (86) postulates that the growth of the crack will occur in a direction perpendicular to the maximum principal stress. As a continuous criterion, the criterion does not take into account the discreteness of the numerical modeling of the crack-extension procedure.

The maximum strain failure criterion is unified with the maximum stress failure criterion, after exploring the implications of two considerations responsible for this: (1) the failure strains for the direct strain components employed in the maximum strain criterion are all defined under uniaxial stress states, not uniaxial strain states, and (2).

According to the theory of maximum principal strain, "The failure of a material or component will occur when the maximum value of principal strain developed in the body exceeds the limiting value of strain i.e. value of strain corresponding to the yield point of the material". Maximum principal stress theory is also termed as Saint Venant theory.

Maximum Principle Strain Theory: This theory also known as Saint Venant's theory. According to this theory the ductile material starts yielding when the maximum principle strain reaches at that value at which yielding occurs in simple tension or we can say that the minimum principle strain value is equal to the yield point strain in simple.

We will study four important failure theories, namely (1) maximum shear stress theory, (2) maximum normal stress theory, (3) maximum strain energy theory, and (4) maximum distortion energy theory. Out of these four theories of failure, the maximum normal stress theory is only applicable for brittle materials, and the remaining three theories.

Material failure theory is an interdisciplinary field of materials science and solid mechanics which attempts to predict the conditions under which solid materials fail under the action of external loads. The failure of a material is usually classified into brittle failure ( fracture) or ductile failure ( yield ).
