Title:Bubble raft model of crystal fatigue TR
Author(s):Sinclair, G.M.; Corten, H.T.; Dolan, Thomas J.
Abstract:Studies were made of the behavior of vacancies and dislocations in a bubble raft model of a crystal which was subjected to completely reversed cyclic shear. It was found that lattice vacancies tend to condense or collect to form the nucleus of a “crack” at a rate which depends on the amplitude of the reversed shear. Growth of the “crack” occurs when additional vacancies are transported to the nucleus by moving dislocations. A possible mechanism of fatigue of metal crystals is suggested in terms of the behavior of imperfections in the bubble model.
