| Abstract: | The problem of the incidence of a shock wave with a front-pressure amplitude of about 30 GPa at the profiled free surface
of an aluminum sample is studied. It is shown that in the case of large perturbations (amplitude 1 mm and wavelength 10 mm), jet flows occur on the free surface. The data obtained are described using a kinetic fracture model that takes into account
the damage initiation and growth in the material due to tensile stress and shear strain.
