Fracture of viscoelastic solids modeled with a modified phase field method
Computer Methods in Applied Mechanics and Engineering, 2019Fracture of viscoelastic solids plays an important role in many applications but it is not yet well understood. In addition to the time and rate dependent response of viscoelastic materials, fracture of these solids is governed by nonlinear processes at ...

Bi-Velocity Phase Field Method
Defect and Diffusion Forum, 2013In this paper we couple the bi-velocity with the phase field method. It deals with: (1) the different mobility of the components in the two-phase zone; (2) nonzero steps of molar volumes for each component from phase to phase and (3) the composition dependent interdiffusion coefficients.

Modeling crack propagation in variable stiffness composite laminates using the phase field method
Composite structures, 2019The fracture processes of the constant/variable stiffness composite laminate (CSCL/VSCL) subjected to uni-axial tension is investigated using the phase-field method. The main objectives of this work are: (a) to study the crack propagation path and (b) to

Fracture modeling of brittle biomaterials by the phase-field method
, 2020Biomaterials have been extensively used in prosthetic applications for their proven biocompatibility and osseointegration characteristics. Nevertheless, one of the critical issues of some synthetic biomaterials is brittleness prone to experience fracture

Phase-Field Method for 2D Dendritic Growth
2004The phase field method is used to model the free dendritic growth into undercooled melt in 2D. The pair of two nonlinear reaction-diffusion equations – for the temperature and for the phase-field function – are solved numerically by using the finite element method in space.

Theoretical and applied fracture mechanics (Print), 2019
In the present work, the phase field method (PFM) is integrated with multiscale extended finite element method (MsXFEM) to simulate crack growth in highly heterogeneous materials i.e. matrix with periodically distributed voids and particles.

Coherent Precipitation — Phase Field Method
2005Phase transformation is still the most efficient and effective way to produce various microstructures at mesoscales, and to control their evolution over time. In crystalline solids, phase transformations are usually accompanied by coherency strain generated by lattice misfit between coexisting phases.

In this study, we use a phase field framework to examine multizone hydraulic fracture propagation in a poroelastic medium from a new perspective. Biot poroelasticity theory is used for coupling the displacement and fluid fields.

Phase-field modeling by the method of lattice Boltzmann equations
Physical Review E, 2010In this paper, at first, a lattice Boltzmann method for binary fluids, which is applicable at low viscosity values, is developed. The presented scheme is extension of the free-energy-based approach to a multi-relaxation-time collision model. Various benchmark problems such as the well-known Laplace law for stationary bubbles and capillary-wave test are
