    - Different theories of failures are developed depending upon physical behavior of materials.

    - St. Venant's theory is also known as maximum principle strain theory.

    - According to this theory, material subjected to complex stresses fail in simple tensile test, when maximum principle strain reaches the value of strain at yield point.

    - St. Venant's theory is represented as shown below for two direction stress.
