Microplasticity, a behavior lies between elasticity and macroplasticity, is not only closely
related to the origin of plasticity in crystalline materials, but also profoundly affects the …

Prior to macroscopic yielding, most materials undergo a regime of plastic activity that cannot
be resolved in conventional bulk deformation experiments. In this pre-yield, or micro-plastic …

In-depth understanding of plastic heterogeneities at grain-level and local deformation
behaviors is pivotal in exploring the mechanical response and fracture mechanism of thin …

Traditional macro-scaled plasticity theories may not be fully valid and accurate in study of
meso-/micro-scaled deformation due to the existence of size effects (SEs). In …

A reduced micromorphic model is formulated in the scope of crystal plasticity and crystalline
cleavage damage. The finite strain formulation utilizes a single additional microvariable that …

Directly tracing the spatiotemporal dynamics of intermittent plasticity at the micro‐and
nanoscale reveals that the obtained slip dynamics are independent of applied stress over a …

Crystal structure determines the distinct deformation mode of crystalline materials and thus
plays a critical role in micro-scale deformation. The micro-deformation mechanism at grain …

Deformed polycrystalline metals tend to develop heterogeneous plastic deformation fields,
as the amount of plastic strain varies spatially, depending on local grain orientation …

Single crystal plasticity based on a representative characteristic length is proposed and
introduced into a homogenization approach based on finite element analyses, which are …

Constitutive formulations have increasingly focused on physically-based approaches that
are less phenomenological and incorporate information from multiple scales. Most …
