A phase field model for elastic-gradient-plastic solids undergoing hydrogen embrittlement [PDF]
Journal of the mechanics and physics of solids, 2020 We present a gradient-based theoretical framework for predicting hydrogen assisted fracture in elastic-plastic solids. The novelty of the model lies in the combination of: (i) stress-assisted diffusion of solute species, (ii) strain gradient plasticity ...

A study of morphology of silicon with femtosecond laser based on phase field model
Materials Research Express, 2022 In this paper, phase field model is employed to simulate the process of femtosecond laser which irradiates on silicon surface. The numerical model is mainly used to study the micro/nano evolution process and the atomic diffusion motion of the system ...

Field dislocation mechanics and phase field crystal models [PDF]
Physical Review B, 2020 A new formulation of the Phase Field Crystal model is presented that is consistent with the necessary microscopic independence between the phase field, reflecting the broken symmetry of the phase, and both mass density and elastic distortion. Although these quantities are related in equilibrium through a macroscopic equation of state, they are ...

Phase-field crystal model with a vapor phase [PDF]
Physical Review E, 2013 Phase-Field Crystal (PFC) models are able to resolve atomic length scale features of materials during temporal evolution over diffusive time scales. Traditional PFC models contain solid and liquid phases, however many important materials processing phenomena involve a vapor phase as well.

A phase field model for cohesive fracture in micropolar continua [PDF]
arXiv.org, 2020 While crack nucleation and propagation in the brittle or quasi-brittle regime can be predicted via variational or material-force-based phase field fracture models, these models often assume that the underlying elastic response of the material is not size-

Monte-Carlo-Assisted Phase Field Simulations of Grain Structure Evolution during the Welding Process
Metals, 2023 A Monte-Carlo-assisted phase field model for the simulation of grain growth in metals and alloys is presented. The simulation time in this model is connected to real time through an experimental data-based kinetic model.

Complex order parameter phase-field models derived from structural phase-field-crystal models [PDF]
Physical Review B, 2013 The phase-field-crystal (PFC) modeling paradigm is rapidly emerging as the model of choice when investigating materials phenomena with atomistic scale effects over diffusive time scales. Recent variants of the PFC model, so-called structural PFC (XPFC) models introduced by Greenwood et al., have further increased the capability of the method by ...
