Spall strength characteristics of a U-1.5% Mo alloy during explosive loading at various intensities

Explosive experiments are performed to determine the conditions of incipient and developed spall fracture in wedge samples of a U-1.5% Mo alloy. All experimental data are described by one empirical dependence, which relates the tensile stresses in a spall plane to the stress gradient in a tension wave and the amplitude of shock-wave compression preceding tension.
