Efficient Meshless Phase-Field Modeling of Crack Propagation by Using Adaptive Load Increments and Variable Node Densities

Mathematics
This study employs the fourth-order phase-field method (PFM) to investigate crack propagation. The PFM incurs significant computational costs due to its need for a highly dense node arrangement for accurate crack propagation.

Crossover scaling functions and an extended minimal subtraction scheme

, 1995
A field theoretic renormalization group method is presented which is capable of dealing with crossover problems associated with a change in the upper critical dimension.

A Quark Transport Theory to describe Nucleon--Nucleon Collisions [PDF]

, 1993
On the basis of the Friedberg-Lee model we formulate a semiclassical transport theory to describe the phase-space evolution of nucleon-nucleon collisions on the quark level.

Consistent, essentially conservative and balanced-force Phase-Field method to model incompressible two-phase flows

Journal of Computational Physics, 2020
In the present work, the Cahn-Hilliard Phase-Field model of incompressible two-phase flows is considered. Conditions needed for consistency of reduction, consistency of mass and momentum transport, and consistency of mass conservation are proposed.

A phase-field-crystal approach to critical nuclei

, 2010
We investigate a phase-field-crystal model for homogeneous nucleation. Instead of solving the time evolution of a density field towards equilibrium we use a String Method to identify saddle points in phase space.

Cell Dynamics Simulation of Kolmogorov-Johnson-Mehl-Avrami Kinetics of Phase Transformation

, 2005
In this study, we use the cell dynamics method to test the validity of the Kormogorov-Johnson-Mehl-Avrami (KJMA) theory of phase transformation. This cell dynamics method is similar to the well-known phase-field model, but it is a more simple and ...

Evolution of Fields in a Second Order Phase Transition [PDF]

, 1994
We analyse the evolution of scalar and gauge fields during a second order phase transition using a Langevin equation approach. We show that topological defects formed during the phase transition are stable to thermal fluctuations.

Modelling progressive failure in multi-phase materials using a phase field method

Engineering Fracture Mechanics, 2019
In this paper, a new phase field method is proposed for modelling of progressive failure in multi-phase materials. Material properties of the interface between inclusion and matrix are regularized by an auxiliary interface phase field. In addition, crack
