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: WebHydrostatic Stress As the hydrostatic stress is unlikely to influence deformation in a solid that deforms at constant volume, it may be surmised that it is the deviatoric components that will be the ones associated with the shape change.
