Continuum-Equivalent Traction Fields: Quantitative Descriptors of Nanoscale Interfaces
Abstract
The authors proposes to identify relationships between the stress (or traction) distribution at a grain boundary to dislocation slip and creep mechanisms. For example, it is hypothesized that the stability of grain boundary (GB) is dictated by how close the tensile and compressive stress peaks are located on the GB and their relative magnitudes. While the idea is interesting, there is no theory available that links tractions to complex behavior like diffusion creep. The relationships are hypothesized by correlating with limited MD data. The transferability of these ideas to a variety of tilt/twist grain boundaries and grain boundary junctions is unclear.
