Atomic Crack Simulation in Fracture Mechanics.

Abstract

Using computer simulation, the authors have attempted to relate the macroscopic fracture properties of bcc iron to phenomena on the atomic scale. Although bonds can be made to rupture in the computer model (brittle fracture), the predicted cleavage plane is the (100) plane. This discrepancy is attributed to the approximations made in the flexible boundary. (Author)
