Plasticity and Creep

TL;DR: In this article, the authors review the basic multiscale physics underlying mylonitic, ductile shear zone nucleation, growth and longevity and show that grain size reduction is a symptomatic cause but not necessarily the main reason for localization.

TL;DR: In this paper, a modified Burgers model has been developed for the studied adhesive with a constant modulus of elasticity for the non-relaxing part (describing the instant elastic strain) and variables, dependent on the tensile stress, the parameter values for its relaxing part.

TL;DR: In this article, a dynamic integro-differential operator of variable order is proposed for a more adequate description of processes, which involve state dependent measures of elastic and inelastic material features.

TL;DR: In this paper, a fully implicit integration scheme is adopted and the relevant expression of the consistent tangent operator for yield criteria and flow functions of arbitrary type is derived by suitably generalizing the approach exploited for rate-independent plasticity.
