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: WebThe deviatoric strain description of the critical properties of Nb 3Sn conductors A. Godeke *, B. ten Haken, H.H.J. ten Kate ... The hydrostatic and the deviatoric invariants are considered in the theory on the su-perconducting state. Comparisons of hydrostatic
