The grain-boundary dislocation arrangement and decomposition during constant-volume deformation of a nanoscale bi-crystal system in fcc-structured materials were studied by using the two-mode phase-field crystal (2PFC) method. effects different grain boundary misorientations (GBMs) tensile directions on are analyzed. In three symmetrical tilt boundaries evaluated PFC, atomic density profile cha...

The concepts of sparse data structures and related algorithms for phase field simulations are discussed. Simulations of polycrystalline grain growth with a conventional phase field method and with sparse data structures are compared. It is shown that memory usage and simulation time scale with the number of nodes but are independent of the number of order parameters when a sparse data structure...

In this paper it has been demonstrated by numerical simulation that the intense second harmonic field induces a nonlinear phase change on a fundamental field simultaneously through the cascaded second-order processes. It has been shown that the phase variation depends on both the propagation distance and the incident fundamental field E1. The phase variation strongly depends on the wavelength o...
