Abstract : By algebraic methods, this paper obtains expressions for the decrement and modulus defect due to the breakaway of a dislocation from a row of equally spaced pinning points, using expressions for the activation energy given in an earlier paper. The model is that of Teutonico, Granato, and Lucke, but incorporating a pinning force of general shape.
