Left cauchy green tensor
Nettet4.2.6 The Left Cauchy-Green Deformation Tensor: The tensor is termed the left Cauchy-Green deformation tensor. As shown above, it is a positive definite symmetric matrix, thus, it has three positive real eigenvalues and three perpendicular eigenvectors. NettetThis paper deals chiefly with various issues pertaining to the existence and uniqueness of a finite deformation that gives rise to a prescribed right or left Cauchy-Green strain …

NettetAlternatively, we can describe the same phenomena from the Eulerian viewpoint. Following the same line of thought as above, we see that Defining the left Cauchy-Green tensor as where , it follows that The Eulerian strain tensor, also called the Almansi strain tensor, is the map defined as follows: Here, is the identity map on .

Nettet13. apr. 2024 · In this section, firstly, a stable data-driven structural analysis (DDSA) algorithm for three-dimensional continuum structures under finite deformation is proposed. Then the effectiveness of DDSA algorithm is verified by a numerical example.
