NettetIn general form, the constitutive equation relates the energy of deformation to the principal stretches, invariants of Cauchy–Green strain tensor, and other material parameters. The development of adequate constitutive equations for living tissues is the topic of an active ongoing research. Nettet27. mai 2024 · C = F T F is called the "Right" Cauchy-Green tensor, and b = F F T is called the "Left" Cauchy-Green tensor. I suppose in C = F T F the non-transposed F stands on the right, and in b = F F T it stands on the left, but I guess there's gotta be more to it? Is there any reason for why they are called "right" and "left" specifically? finite …
