WebApr 1, 2014 · Various such tensors exist, e.g. the Green strain tensor 1 2 (U 2 − 1), the generalized Green strain tensor 1 m (U m − 1), where m is a nonzero integer, and the Hencky (or logarithmic) strain tensor log U. In linearized elasticity, one considers φ (x) = x + u (x), where u: Ω ⊂ R 3 → R 3 is the displacement. The classical linearized ... The concept of strain is used to evaluate how much a given displacement differs locally from a rigid body displacement. One of such strains for large deformations is the Lagrangian finite strain tensor, also called the Green-Lagrangian strain tensor or Green – St-Venant strain tensor, defined as or as a function of the displacement gradient tensor
