The normal …
WebThe principal values of a Green strain tensor will be principal Green strains. Everything below follows from two facts: First, the input stress and strain tensors are symmetric. Second, the coordinate transformations discussed here are applicable to stress and strain tensors (they indeed are). We will talk about stress first, then strain. WebGreen's strain matrix is, thus, available directly from the deformation gradient without first having to solve for the principal directions. This advantage makes Green's strain computationally attractive. Recall that strain is the link between the kinematics and the constitutive theory, so the strain choice should be optimal based on the two ...
