Electrical treeing: A phase-field model
Extreme Mechanics Letters, 2019 Electrical treeing is a commonly observed phenomenon associated with dielectric breakdown in solid dielectrics. In this work, a phase-field model is developed to study the initiation and propagation of electrical trees in two different geometries: a ...

A Phase Field Model for Rate-Dependent Ductile Fracture
Metals, 2017 In this study, a phase field viscoplastic model is proposed to model the influence of the loading rate on the ductile fracture, as one of the main causes of metallic alloys’ failure.

Numerical Phase-Field Model Validation for Dissolution of Minerals
Applied Sciences, 2021 Modelling of a mineral dissolution front propagation is of interest in a wide range of scientific and engineering fields. The dissolution of minerals often involves complex physico-chemical processes at the solid–liquid interface (at nano-scale), which ...

Phase-field modeling of eutectic growth
Physical Review E, 2000 A phase-field model of eutectic growth is proposed in terms of a free energy F, which is a functional of a liquid-solid order parameter psi, and a conserved concentration field c. The model is shown to recover the important features of a eutectic phase diagram and to reduce to the standard sharp-interface formulation of nonequilibrium growth.

Sharp-Interface Limit of a Fluctuating Phase-Field Model
, 2005 We present a derivation of the sharp-interface limit of a generic fluctuating phase-field model for solidification. As a main result, we obtain a sharp-interface projection which presents noise terms in both the diffusion equation and in the moving ...
