WebThe above relationship shows that nonzero volumetric strains exist only when the hydrostatic stress is nonzero. To separate the volumetric from the deviatoric strain energy functions, the deviatoric stress will be used. By replacing with and in Equation 2 the following is obtained: (5) The right hand side can be separated into two terms: WebTherefore, the strain is habitually related to how far away stress is from the isotropic state. The deviatoric stress expresses this difference by subtracting the mean stress from the stress tensor. Considering that any general state of stress is the sum of the hydrostatic mean stress p and the deviatoric stress:
