Webdeformation, i.e. change of length of a vector AND rigid body rotation is only provided by the displacement gradient tensor H or by the transformation tensor F. 3. Lagrange strain tensor The Lagrange description of strain is similar to the Cauchy-Green description of the quadratic strain (Equation 9). WebIn the constitutive models in Abaqus εth= εth(θ) ε t h = ε t h ( θ) only. This form of decomposition of the deformation depends on ε ε being measured as the integrated rate of deformation and on the elastic and thermal strains being small: this is true for the standard plasticity models provided in the program. cost to foreclose on a property
