Materials Research Express, 2021 In the polycrystalline solid-state electrolytes (SSEs), ionic transport is directly linked to the properties of all solid-state batteries. Grain boundaries (GBs), as essential defects in SSE, were found to play a significant role in the overall kinetics ...

Phase-Field Models with Hysteresis
Journal of Mathematical Analysis and Applications, 2000 Phase-field systems as mathematical models for phase transitions have drawn increasing attention in recent years. However, while capable of capturing many of the experimentally observed phenomena, they are only of restricted value in modelling hysteresis effects occurring during phase transition processes. To overcome this shortcoming of existing phase-

Phase Field Modeling of Dendritic Growth on Spherical Surfaces
Frontiers in Materials, 2020 The spontaneous formation of a crystal phase is one of the most common and beautiful pattern formation mechanisms in nature. Different instabilities in the crystal interface may lead to the growth of ramified structures, known as dendritic crystal growth.

Phase Field Methods and Dislocationss
MRS Proceedings, 2000 We present a general formalism for incorporating dislocations in Phas Field methods. This formalism is based on the elastic equiva;ence betweem a dislocation loop and a platelet inclusion of specific stress-free strain related to the loop Burgers vector and normal.

A Generalized Phase-Field System
Journal of Mathematical Analysis and Applications, 1999 The authors consider the problem \((\Omega\) bounded domain in \(\mathbb{R}^N\) with \(C^2\)-boundary) \[ \begin{aligned} {\partial u\over\partial t}+l {\partial \varphi\over\partial t}=\Delta u+f(x,t), \quad & (x,t)\in Q:=\Omega \times(0,T),\\ {\partial\varphi \over\partial t}=\Delta\varphi+ F(x,t,\varphi) +u,\quad & (x,t)\in Q,\\ {\partial u\over ...

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 ...

CoRRPeridynamics formulates the balance of linear momentum as an integro-differential equation, making it naturally suited for fracture modeling without special treatment of discontinuities. The bond-associated correspondence formulation provides a highly accurate peridynamic framework by computing bond-wise deformation gradients that are free of zero ...
