On the conditions for the onset of motion of two collinear dislocation discontinuities
The conditions under which the motion begins of two collinear dislocational Volterra-type discontinuities, initially specified on a single straight line in a homogeneously isotropic elastic medium, is studied. The theory of invariant \(\Gamma\)-integrals [\textit{G. P. Cherepanov}, Mechanics of brittle fracture (1979; Zbl 0442.73100)] is used to write the criteria defining the beginning and direction of motion of either end of the discontinuity. The limiting stresses are determined and the subsequent behaviour of the whole system is investigated.
