Modeling of crack deflection/penetration as intergranular/transgranular fracture in the polycrystal under the coupled thermo-gaseous-mechanical multi-physics field has long been a challenge for both fracture mechanics and materials science. The curre

A phase-field model combined with CALPHAD thermodynamic database was employed to investigate the microstructure evolution of δ-hydride in Zr alloys during isothermal aging. The results showed that under the elastic strain energy, a small δ-hydride

In this paper, we first propose a novel fully-decoupled, linear and second-order time accurate scheme to solve the phase-field model of non-Newtonian two-phase flows; the developed scheme is based on a stabilized Scalar Auxiliary Variable (SAV) appro

Abstract Both irradiation and dislocations have been proposed as routes to rationally manipulate spatial distribution and micromorphology of precipitate. An interesting effect emerges in Fe–10at.%Cu–3at.%Mn–1.5at.%Ni–1.5at.%Al alloy due to th

Geologic fractures such as joints, faults, and slip surfaces govern the stability and performance of many subsurface systems in the built environment. As such, a variety of approaches have been developed for computational modeling of geologic fractur

Extensive research has explored cracking in asphalt mixtures under pure mode-I conditions; however, heavy traffic loads often lead to crack formation under mixed-mode fracture conditions in asphalt pavements. This paper presents a phase field damage
