Propagation of discontinuity surfaces of strong and weak discontinuity in elasto-visco-plastic media

Definitions

Surfaces of weak and strong discontinuity in elasto-visco-plastic media are the transient waves carrying the jumps in the field parameters on the wave front; in so doing the magnitudes of plastic deformations should be continuous on the surface.

Preliminary Remarks

Propagation and attenuation of weak and strong discontinuities in a viscoelastoplastic medium have been investigated under the Mises yield condition in Bykovtsev and Verveiko (1966), wherein it has been shown that two types of waves could exist in such a medium: irrotational and equivoluminal, their velocities of propagation have been calculated, and relationships describing the variation in wave intensity during propagation have been derived.

In the present entry, the behavior of strong and weak discontinuities in the same sort of a medium under the Tresca yield condition and the maximal reduced stress...
