WebThe left and right Cauchy Green deformation tensors are, respectively, (3.1.35) The finite strain tensor is (3.1.36) The principal invariants of B (or C) are (3.1.37) It proves to be convenient to replace these invariants by the invariants (3.1.38) WebHere denotes the modified right Cauchy-Green tensor and is the unimodular (distortional) part of the deformation gradient F, with J = der F > 0 denoting the local volume ratio. In addition, in Eq. 1, { A1, A2 } is a set of two (second-order) tensors which characterize the anisotropic properties of the tissue at any X.

Webright Cauchy-Green strain tensor CR ¼ FTF. This special material line, as the “skeleton” of the fluid element, can be used to reflect the overall geometry of the fluid element. Substituting eˆ ¼ ˆe R1 in Eq. (2) results in the quadratic equation xðλÞ¼rs 1λþrb 1λ 2 where rs 1 ¼ F· eˆ R and rb 1¼ eˆ R·G· ˆe . An example of ...

As shown above, it is a positive definite symmetric matrix, thus, it has three positive real eigenvalues and three perpendicular eigenvectors. WebThe right Cauchy-Green deformation tensor (named after Augustin Louis Cauchy and George Green) is defined as:: or The spectral decomposition of is Physically, the Cauchy-Green tensor gives us the square of local change in distances due to deformation.
