Grain boundaries and crystalline plasticity
WebThe grain boundary refers to the outside area of a grain that separates it from the other grains. The grain boundaries separate variously-oriented crystal regions … WebMar 1, 2007 · A crystal plasticity finite element (CPFE) model of the indentation geometry was built to simulate both the single crystal and the near grain boundary indentation (bi-crystal indentation) deformation process. The accuracy of the model is evaluated by comparing the point-wise volumetric differences between simulated and experimentally …

WebAs can be inferred from Fig. 4 d, this is due to the interplay between dislocation density and grain morphology; plasticity is shown to be concentrated at some bands parallel to the grain boundaries in the [100] grains. Hence, grain boundaries are shown to act as barriers or preferential directions of crack growth. WebGRAIN BOUNDARIES AND Crystalline Plasticity by L. Priester (English) Hardcover B - $412.47.
