Abstract: A macroscopic formulation of large deformations elastoplasticity with tensorial structure variables is presented. The novel features are the effect of constitutive relations for the plastic spin ...

Abstract: To illustate the effect of the choice of corotational rates at large plastic deformations, expressions for the stresses developing in large simple shear are obtained in closed analytical form ...

Abstract: The notion of Plastic Internal Variables (PIV ) is used in reformulating, in a general form, the equations of rate-independent plasticity. The stress, temperature, and the PIV are the state ...

Abstract: The coaxial and totally noncoaxial parts of a tensor in regard to another reference tensor are derived in closed analytical form based on representation theorems of tensor-valued isotropic functions. In the process a new ...

Abstract: Recent laboratory investigations indicate that the stress–strain–strength responses of granular soils are appreciably affected by the fabric orientation of the soil relative to the frame of principal stresses. Especially, ...
