Phase-Field Crystals with Elastic Interactions [PDF]
Physical Review Letters, 2006 We report on a novel extension of the recent phase-field crystal (PFC) method introduced in [Elder et al., Phys. Rev. Lett., Vol. 88, 245701:1-4 (2002)], which incorporates elastic interactions as well as crystal plasticity and diffusive dynamics. In our model, elastic interactions are mediated through wave modes that propagate on time scales many ...

Phase-field approach for faceted solidification [PDF]
Physical Review E, 2003 We extend the phase-field approach to model the solidification of faceted materials. Our approach consists of using an approximate gamma-plot with rounded cusps that can approach arbitrarily closely the true gamma-plot with sharp cusps that correspond to faceted orientations.

Phase Field Analysis of Eutectic Breakdown [PDF]
Metallurgical and Materials Transactions A, 2007 In this article, an isotropic multi-phase-field model is extended to include the effects of anisotropy and the spontaneous nucleation of an absent phase. This model is derived and compared against a published single-phase model. Results from this model are compared against results from other multiphase models; additionally, this model is used to ...

Convergence Check Phase-Field Scheme for Modelling of Brittle and Ductile Fractures
Applied Sciences, 2023 The paper proposes a novel staggered phase-field framework for modelling brittle and ductile fractures in monotonic and cyclic loading regimes. The algorithm consists of two mesh layers (displacement and phase field) and a single special-purpose, user ...

Sharp interface limits of phase-field models [PDF]
, 2000 The use of continuum phase-field models to describe the motion of well-defined interfaces is discussed for a class of phenomena, that includes order/disorder transitions, spinodal decomposition and Ostwald ripening, dendritic growth, and the ...

Phase-field-crystal models for condensed matter dynamics on atomic length and diffusive time scales: an overview [PDF]
, 2012 Here, we review the basic concepts and applications of the phase-field-crystal (PFC) method, which is one of the latest simulation methodologies in materials science for problems, where atomic- and microscales are tightly coupled. The PFC method operates

Membranes, 2022 The working principle of lateral flow assays, such as the widely used COVID-19 rapid tests, is based on the capillary-driven liquid transport of a sample fluid to a test line using porous polymeric membranes as the conductive medium.

The deviation from eutectic composition in boundary layer for eutectic growth: a phase-field study [PDF]
Archives of Metallurgy and Materials, 2019 In this paper, the deviation from eutectic composition in boundary layer for eutectic growth is studied by phase-field method. According to a series of artificial phase diagram, the lamellar eutectic growth of these alloy is simulated during directional ...
