A thermodynamics-based model for brittle to ductile behaviour and localised failure of porous rocks

TL;DR: An elastoplastic damage constitutive model, based on the super/subloading yield surfaces, is proposed for frozen soil, in which the damage variable and bond strength are used to consider the elastic and plastic damage respectively as discussed by the authors.

TL;DR: In this article , a phase-field approach for capturing the formation and propagation of compaction bands is proposed, where the fracture energy utilized in classic phase field formulations is interpreted to be driven by grain crushing and is characterized by breakage mechanics theory.

TL;DR: In this article, a thermodynamic extension of the thermomechanics theory to account for poromechanic complexity of path-and rate-dependent critical state line models for porous rocks is presented.

TL;DR: In this article, a generic thermodynamics-based approach is proposed to coupling the effects of deformation and saturation in modelling partially saturated soils taking into account the interdependence of all internal variables.

TL;DR: De Borst et al. as discussed by the authors present a condensed version of the original book with a focus on non-linear finite element technology, including nonlinear solution strategies, computational plasticity, damage mechanics, time-dependent effects, hyperelasticity and large-strain elasto-plasticity.

TL;DR: De Borst et al. as mentioned in this paper present a condensed version of the original book with a focus on non-linear finite element technology, including nonlinear solution strategies, computational plasticity, damage mechanics, time-dependent effects, hyperelasticity and large-strain elasto-plasticity.

TL;DR: In this paper, the authors investigated the hypothesis that localization of deformation into a shear band may be considered a result of an instability in the constitutive description of homogeneous deformation.

TL;DR: The fundamental assumption of all theories of plasticity, that of time independence of the equations of state, makes simultaneous description of the plastic and rheologic properties of a material impossible as mentioned in this paper.
