WebNov 9, 2015 · With the aim of simulating a Frank-Read source, a dislocation source model is developed for a pure Nickel system. By varying the length of the source model, insights into the mechanism of ... In materials science, a Frank–Read source is a mechanism explaining the generation of multiple dislocations in specific well-spaced slip planes in crystals when they are deformed. When a crystal is deformed, in order for slip to occur, dislocations must be generated in the material. This implies that, during … See more Charles Frank detailed the history of the discovery from his perspective in Proceedings of the Royal Society in 1980. In 1950 Charles Frank, who was then a research fellow in the physics department at the See more The Frank–Read source is a mechanism based on dislocation multiplication in a slip plane under shear stress. Consider a straight dislocation in a crystal slip plane with its two ends, A and B, pinned. If a shear stress $${\displaystyle \tau }$$ is … See more
