Over the last three decades, a number of researchers have used the gradient-enhanced
plasticity theory to model the microstructural material behavior, which is not able to be …

Gradient grained metals whose microstructure is characterized by a spatially graded grain
size distribution show a better strength-ductility combination than their homogeneous …

A standard experimental method for determining the intrinsic material length scale of
modified couple stress theory is proposed based on a non-contact laser Doppler vibration …

A microstructure-based integrated crystal plasticity (CP) and continuum damage mechanics
(CDM) model is proposed for simulating rolling contact fatigue (RCF). The damage process …

Multi-scale models enriched with the second gradient of the displacement field and based
on the concept of representative volume element (RVE) are examined and discussed in …

A multiscale modeling methodology involving discrete dislocation dynamics (DDD) and
crystal plasticity finite element method (CPFEM) was used to study the grain size effect in …

The use of Nye's dislocation tensor for calculating the density of geometrically necessary
dislocations (GND) is widely adopted in the study of plastically deformed materials. The …

Size effects (SEs) impede the mass production of high-performance miniaturised
components via micro-forming. Although many studies have examined SEs from multiple …

Abstract A three-dimensional (3D) peridynamics (PD) model of crystal plasticity (CP) is
presented for predicting the fine-scale localization in polycrystalline microstructures …

Differential form of Eringen's nonlocal elastic theory has some inaccuracies in analyzing
small-scale structures with different boundary conditions. For this reason, Eringen's two …
