Learn More ### Failure Theories—Static Loading

3. Each theory relates the state of stress to a measurable criterion of failure In general all failure theories say the same thing: When the maximum value of stress or strain in a multi-axial state of stress equals or exceeds the value of stress or strain that produces failure in a uni-axial stress test, the part fails. Maximum Normal Stress Theory

The principal theories of failure for a member are as follows:(Any four) (i) Maximum principal or normal stress theory (ii) Maximum shear stress theory (iii) Maximum principal or normal strain theory (iv) Maximum strain energy theory (v) Maximum distortion energy theory Maximum normal stress theory According to this theory, the elastic failure occurs when the greatest

Learn More ### What are the various Theories of Failure under

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.

Deformation in continuum mechanics is the transformation of a body from a reference configuration to a current configuration. A configuration is a set containing the positions of all particles of the body. A deformation may be caused by external loads, body forces (such as gravity or electromagnetic forces), or changes in temperature, moisture content, or chemical reactions, etc.

American sociologist Robert K. Merton developed strain theory, a concept connected to both the functionalist perspective on deviance and Émile Durkheim's theory of anomie.Merton asserted that societies are composed of two core aspects: culture and social structure.Our values, beliefs, goals, and identities are developed in the cultural realm.

Maximum Normal Stress Criterion. The maximum normal stress criterion also known as Coulomb's criterion is based on the Maximum normal stress theory. According to this theory failure occurs when the maximum principal stress reaches the ultimate strength of the material for simple tension. This criterion is used for brittle materials.

Learn More ### Stress, Strain and Young's Modulus -

Stress. Stress is the ratio of applied force F to a cross section area-defined as "force per unit area".. tensile stress - stress that tends to stretch or lengthen the material - acts normal to the stressed area; compressive stress - stress that tends to compress or shorten the material - acts normal to the stressed area; shearing stress - stress that tends to shear the material - acts in
