WebBut each log term is just the true strain. In fact, the sum is the trace of the true strain tensor. \[ \epsilon^\text{True}_1 + \epsilon^\text{True}_2 + \epsilon^\text{True}_3 = 0 \qquad \text{(incompressible materials)} \] Unlike small strains and Green strains, the above relationship applies to true strains even when the strains are finite. WebThe Green-Lagrange strain tensor is directly defined in function of the right strain tensor by E = (C −I)/2, where I is the identity tensor, and its components are noted E ij with i, j = 1, …, 3. As the strain tensor components, values depend on the basis in which they are written, some use the strain invariants to express the constitutive law.
