【 摘 要 】

The dynamics of fracture of liquid cube with high-pressure cavity is studied numerically in a three-dimensional formulation using the Smoothed Particle Hydrodynamics method (SPH). It is shown that the propogation of shock wave from growing cavity and reflection from the free side is due to relaxation of tensile stresses in the liquid volume and formation of quasistationary mass-velocity field which provides fracture of the fluid.
