Effect of shear-coupled grain boundary motion on coherent precipitation
Marc Weikamp, Robert Spatschek
We examine the interaction between precipitates and grain boundaries, which undergo shear-coupled motion. The elastic problem, emerging from grain boundary perturbations and an ela…
Critical nucleation length for accelerating frictional slip
Michael Aldam, Marc Weikamp, Robert Spatschek +2
The spontaneous nucleation of accelerating slip along slowly driven frictional interfaces is central to a broad range of geophysical, physical and engineering systems, with particu…
Non-linear elastic effects in phase field crystal and amplitude equations: Comparison to ab initio simulations of bcc metals and graphene
C. Hüter, M. Friák, M. Weikamp +4
We investigate non-linear elastic deformations in the phase field crystal model and derived amplitude equations formulations. Two sources of non-linearity are found, one of them ba…
Dynamic instabilities of frictional sliding at a bimaterial interface
Efim A. Brener, Marc Weikamp, Robert Spatschek +2
We study the 2D linear stability analysis of a deformable solid of a finite height , steadily sliding on top of a rigid solid within a generic rate-and-state friction type const…
