Severe plastic deformation (SPD) has established itself as a potent means of producing bulk
ultrafine grained and nanostructured materials. It has given rise to burgeoning research that …

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 …

A combined experimental and strain gradient crystal plasticity framework is presented for
studying the development of orientation and misorientation gradients at the grain …

Nonlocal effects permeate most microstructured materials, including granular media, metals
and foams. The quest for predictive nonlocal mechanical theories with well-defined internal …

Strain gradient plasticity theory addresses the plastic strain gradient induced hardening by
considering the internal stress and Taylor hardening associated with the geometrically …

The physical basis and the magnitude of the material length scale in theories of strain
gradient plasticity are crucial for accounting for size effects in the plastic behavior of metals …

The size effect, the passivation effect, and the plastic behavior under non-proportional
loading in the context of bending and tension of thin foils, and a combination of compression …

This study unveils the presence of size effect not only in the plastic regime but also in the
elastic regime under strain gradient. This discovery emerges from a comprehensive set of …

Torsion experiments on copper wires with different diameters but the same grain size are
performed to figure out the individual contribution of plastic strain gradient to size effect. The …

This work looks into the passive failure of tunnel head in strain-softening soils modeled
using a nonlocal constitutive model. The Drucker–Prager yield criterion and plastic potential …
