TL;DR: In this paper, a micromechanical model that assesses a nonlinear coupling between statistically stored dislocations (SSDs) and geometrically necessary dislocation (GNDs) is used to derive an analytical form for the deformation-gradient-related intrinsic length-scale parameter in terms of measurable microstructural physical parameters.

TL;DR: In this article, a plastic-damage constitutive model for plain concrete is developed to account for different effects under tensile and compressive loadings, two damage criteria are used: one for compression and a second for tension such that the total stress is decomposed into tensile or compressive components.

TL;DR: In this paper, the authors developed microstructural physical based constitutive models to characterize the deformation behavior of body centered cubic (bcc) and face centered cubic(fcc) metals under different strain rates and temperatures.

TL;DR: In this article, a coupled theory of continuum damage mechanics and finite strain plasticity with small elastic strains is formulated in the Eulerian reference system, and an explicit matrix representation is derived for the damage effect tensor for a general state of deformation and damage.
