Contribution of meso- and macroscale energy exchange to the propagation of steady plastic waves

The collective processes involved in the macroscopic response of metals to shock loading are considered on the basis of momentum and energy exchanges between the meso- and macroscale levels of deformation. The test problem under study is the propagation of a steady plastic front. The analytical solution derived for the steady front from dislocation dynamics is supplemented with an expression relating the velocity defect to the particle velocity. It is shown that in this case, calculated and experimental profiles are found coincident.
