This paper reviews recent studies, that not only includes both experiments and modeling
components, but celebrates a close coupling between these techniques, in order to provide …

In a material under stress, grain boundaries may give rise to stress discontinuities. Stress
localization is crucial to materials' behavior such as segregation, precipitation, and void …

Abstract Spectral methods using Fast Fourier Transform (FFT) algorithms have recently seen
a surge in interest in the mechanics of materials community. The present contribution …

The dislocation density tensor computed as the curl of plastic distortion is regarded as a new
constitutive variable in crystal plasticity. The dependence of the free energy function on the …

A new microstructure-informed three-scale homogenization scheme for elasto-viscoplastic
heterogeneous materials is developed. It is applied to predict the mechanical behavior of …

Incompatibility stresses can develop in bicrystals due to material elastic and plastic
anisotropies owing to different crystal orientations separated by grain boundaries. Here …

A complete micromechanics-based model is here proposed using the concepts of
continuum kinematics and thermodynamics. A new constitutive framework is proposed to …

Grain boundary (GB) resistance to slip transmission was investigated computationally and
experimentally as a function of GB type. A geometry-based computational method quantified …

All grain boundaries are not equal in their predisposition for fracture due to the complex
coupling between lattice geometry, interfacial structure, and mechanical properties. The …

From a mathematical point of view, phase field theory can be understood as a smooth
approximation of an underlying sharp interface problem. However, the smooth phase field …
