Phase Field Modeling of Crack Growth with Viscoplasticity

open access: yesCrystals, 2023
The fracture of viscoplastic materials is a complex process due to its time-dependent and plastic responses. Numerical simulation for fractures plays a significant role in crack prediction and failure analysis.

Acceleration and Parallelization of a Linear Equation Solver for Crack Growth Simulation Based on the Phase Field Model

open access: yesMathematics, 2021
We aim to accelerate the linear equation solver for crack growth simulation based on the phase field model. As a first step, we analyze the properties of the coefficient matrices and prove that they are symmetric positive definite. This justifies the use

On validating peridynamic models and a phase-field model for dynamic brittle fracture in glass

open access: yes, 2020
We test two peridynamic models and one phase field model against recent experimental tests on dynamic fracture/crack branching in glass induced by impact.

Modelling of Microstructure Formation in Metal Additive Manufacturing: Recent Progress, Research Gaps and Perspectives

open access: yesMetals, 2021
Microstructures encountered in the various metal additive manufacturing (AM) processes are unique because these form under rapid solidification conditions not frequently experienced elsewhere.

Phase field modeling of multiple dendrite growth of Al-Si binary alloy under isothermal solidifi cation [PDF]

open access: yesChina Foundry, 2008
Phase field method offers the prospect of being able to perform realistic numerical experiments on dendrite growth in metallic systems. In this study, the growth process of multiple dendrites in Al-2-mole-%-Si binary alloy under isothermal solidifi ...

On the Diffuse Interface Models for High Codimension Dispersed Inclusions

open access: yesMathematics, 2021
Diffuse interface models are widely used to describe the evolution of multi-phase systems of various natures. Dispersed inclusions described by these models are usually three-dimensional (3D) objects characterized by phase field distribution.

A phase-field model for fatigue crack growth

open access: yesJournal of the mechanics and physics of solids, 2019
A phase-field model is presented for the study of fatigue crack growth. A crack growth viscosity parameter is introduced into the standard phase-field model for brittle fracture to account for rate- or cycle-dependent crack growth phenomena. A modified J-
