Phase-field simulation of fracture in Polymethyl Methacrylate

Mechanics of Advanced Materials and Structures, 2023
Significant interest and developments have emerged in phase-field fracture modeling. The method approximates fracture continuously by introducing a length-scale parameter, accurately simulating fracture initiation and crack propagation in brittle materials like polymethyl methacrylate (PMMA) with nonlinear elasticity.

Phase-Field Simulations of Crystal Growth

AIP Conference Proceedings, 2010
This course gives an elementary introduction to the phase‐field method and to its applications for the modeling of crystal growth. Two different interpretations of the phase‐field variable are given and discussed. It can be seen as a physical order parameter that characterizes a phase transition, or as a smoothed indicator function that tracks domain ...

Phase-field simulation of early-stage kinetics evolution of γ' phase in medium supersaturation Co-Al-W alloy

, 2020
The early precipitation of γ'-Co3(Al, W) phase affects the spatial distribution and kinetic evolution of precipitates for the morphology transmission effect, but the nucleation and concomitant growth are not studied still by aging experiments due to the ...

Phase-field-crystal simulation of nonequilibrium crystal growth

Physical Review E, 2014
By using the phase field crystal model, we simulate the morphological transition of the crystal growth of equilibrium crystal shape, dendrite, and spherical crystal shape. The relationship among growth morphology, velocity, and density distribution is investigated.
