| الوصف: |
In this work, a computational framework for discrete dislocation dynamics simulations of bcc metals, which naturally accounts for non-Schmid effects on a/2 screw dislocation mobility based on atomistic simulation results, is developed. The model describes a physical basis to explain many experimental observations on bcc metals. The role of dislocation interactions towards plastic flow are studied. A new mechanism responsible for anomalous slip in micrometer sized W pillars is identified. |
