This work aims to give a comprehensive and accurate view of those micromechanical
models that have been developed over the past two decades by our research team. We …

In this study, a microdamage model by introducing the damage of crystal is proposed.
Damage variables are defined for each slip system, and the damage-coupled crystal …

Cyclic loading is the main contributor to fatigue failures in mechanical components. In this
paper, the fatigue deformation behavior of nickel-based single crystal superalloys was …

This paper presents a plastic-damage formulation and a new isotropic hardening law, based
on the Barcelona plastic damage model initially proposed by Lubliner et al.(1989)[1], which …

The fatigue plasticity mechanisms and local defect characteristics of engineering materials
are critical for addressing fatigue damage. This study aims to identify the formation …

In this paper, a multiscale model of ductile damage and its effects on the inelastic behavior
of face centered cubic polycrystalline metallic materials, such as the evolution of their …

The Armstrong–Frederick type kinematic hardening rule was invoked to capture the
Bauschinger effect of the cyclic plastic deformation of a single crystal. The yield criterion and …

Motivated by a simplified self-consistent model proposed recently (Abdul-Latif, A., Dingli, J.
Ph., Saanouni, K., 1999b. Elastic–inelastic self-consistent model of polycrystals. submitted) …

The elasto-viscoplastic Taylor–Lin model of polycrystal plasticity is employed to simulate the
cyclic behavior of polycrystalline metals. Uniaxial tension–compression as well as biaxial …

The purpose of this work is to model the mechanical behavior of nanocrystalline materials.
Based on previous rigid viscoplastic models proposed by Kim et al.(Acta Mater, 48: 493 …
