Kinetics for dislocation structure formation in contact area of squeezed crystalline solids

Evolution of dislocation structure during formation of the contact area was studied in modeling experiments "wedge-plane" for KCl single crystal under loading at room and high (0.8Tm) temperatures. It was shown that at the first (rapid) stage of the process, a quasi-stationary dislocation...
