Severe plastic deformation (SPD) techniques such as laser shock peening (LSP) have been
widely adopted to modify microstructure of materials. Understanding the plastic deformation …

In this paper we review the work related to amorphization under mechanical stress. Beyond
pressure, we highlight the role of deviatoric or shear stresses. We show that the most recent …

In the last few decades, a variety of brittle materials (ceramics and glasses) have found new
applications in the armor, nuclear and semiconductor, and energy storage industries …

Boron carbide is extremely hard but has been shown to undergo stress-induced
amorphization when subjected to large nonhydrostatic stresses. This localized …

Adiabatic shear band (ASB) is an important failure mode of solid materials, especially for
metal materials under high strain rate loading. In this study, a thermo-elastic-plastic phase …

In Part I, a thermo-elastic-plastic phase-field model is established for describing the
adiabatic shear band (ASB) in metal materials. In this Part II, the developed model is used to …

Shock compression subjects materials to a unique regime of high quasi-hydrostatic pressure
and coupled shear stresses for durations on the order of 1–10 nanoseconds for laser-driven …

A micromechanical multi-physics model for ceramics has been recalibrated and used to
simulate impact experiments with boron carbide in abaqus. The dominant physical …

Current numerical methods cannot simulate well three-dimensional (3D) fracture process of
solids. In order to study 3D fracture process of brittle-like materials and improve crack growth …

We describe models for the behavior of hot‐pressed boron carbide that is subjected to
extreme dynamic environments such as ballistic impact. We first identify the deformation and …
