Abstract
The early stage of the stable mode III crack growth is theoretically analyzed. A tip of the initial crack is blunted by screw dislocations continuously distributed on two slip-planes inclined at equal angles to the crack. It is assumed that at some critical load level the crack starts to grow and that, with a small increase in the applied load, the crack extends over a small distance and then stops due to the formation of a secondary pair of slip-lines. The boundary value problem relevant to this growth step is formulated by use of the notion of the effective friction stress and solved. The increment of the crack shearing displacement at the site of the initial crack tip is expressed as a function of the crack growth distance and the increment of the applied load. It is found that the form of the function is identical with that previously obtained by J.R. Rice and E.P. Sorensen.
