Physics:Strain-rate tensor - HandWiki
WebThe physical interpretation of the invariants depends on what tensor the invariants are computed from. For any stress or strain tensor, \(I_1\) is directly related to the hydrostatic component of the that tensor. This is universal. \(I_2\) tends to be related more to the deviatoric aspects of stress and strain, although not exclusively. WebThus, every tensor A can be represented as a sum of two tensors; one of these, αI, is an isotropic tensor, and the other, A (d), is a tensor whose trace is 0.Expressions (2.12.1) and (2.12.4) show that A (d) and α are uniquely determined by A.As such, the representation (2.12.5) is unique. The part αI of this representation is called the spherical part of A and … WebWe divide by two to come up with our final definition of the finite strain tensor in terms of the deformation gradient tensor as: We will expand the above expression for one normal and one shear stress.
