Green strain formula
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. http://micro.stanford.edu/~caiwei/me340b/content/me340b-lecture01-v03.pdf
