Question

Explain octahedral shear stress theory.

Answer 1

OCTAHEDRAL SHEAR STRESS THEORY

Octahedral Shear Stress Theory popularly known as von Mises Criterion or Mises-Hencky forecasts failure through yielding once the octahedral shear stress to some degree obtains a specific value. The value is verified through the connection of a simple stress test.

Octahedral Shear stress theory recommends that the giving away of materials starts once the second deviatoric pressure invariant reach the critical value. Because of this, sometimes it is termed the plasticity flow theory
