Some new data on deformation and fracture of solids under shock-wave loading

The topics considered are poorly understood aspects of the high-rate deform ation and fracture under shock-wave loading, and some new kinds of shock-wa ve experiments. A high mobility of the crystal lattice behind the shock fro nt as a result of formation of many stacking faults, unexpectedly high dyna mic yield strength of metals at elevated temperatures as a result of viscou s dislocation drag and spontaneous nucleation of point defects, spall stren gth of metals at temperatures up to the melting point, use of the line imag ing interferometer technique to study a relationship between trans-granular and inter-granular dynamic strength of a polycrystalline metal, and inelas tic deformation and fracture of glasses under impact loading are discussed.
