http://esag.harvard.edu/rice/e3_Mech_Finite_Def.pdf Several rotation-independent deformation tensors are used in mechanics. In solid mechanics, the most popular of these are the right and left Cauchy–Green deformation tensors. Since a pure rotation should not induce any strains in a deformable body, it is often convenient to use rotation … Se mer In continuum mechanics, the finite strain theory—also called large strain theory, or large deformation theory—deals with deformations in which strains and/or rotations are large enough to invalidate assumptions inherent in Se mer The deformation gradient tensor $${\displaystyle \mathbf {F} (\mathbf {X} ,t)=F_{jK}\mathbf {e} _{j}\otimes \mathbf {I} _{K}}$$ is … Se mer A representation of deformation tensors in curvilinear coordinates is useful for many problems in continuum mechanics such as nonlinear shell theories and large plastic deformations. Let Se mer • Infinitesimal strain • Compatibility (mechanics) • Curvilinear coordinates • Piola–Kirchhoff stress tensor, the stress tensor for finite deformations.
