Which mechanism amplifies dislocation movement within a crystal structure?

💡 Explanation

The Frank-Read source creates new dislocations with existing ones because applied stress bows out a dislocation pinned at two points to nucleate more dislocation loops; therefore plasticity increases, rather than effects caused by grain boundaries.
