Abstract

This paper studied the interaction mechanism between the dynamic crack and the precast static crack (horizontal angle for 90° and 150°) under the action of explosion stress and the dynamic behavior of crack propagation using the digital laser dynamic caustics test system. The results show that before the dynamic crack and static crack coalescence, the caustics speckles will occur at both ends of the static crack, while after the dynamic crack and static crack coalescence, the static crack extends in the horizontal direction with a speed lower than that of both the dynamic crack and the crack expansion without static crack; that when the static crack exists, the overall length of the dynamic crack expansion is reduced, the crack initiation time is shortened, the expansion speed is not affected by the static crack, and the stress intensity factor of the crack is greater than that of the static crack; and that as the horizontal angle of the static crack increases, the deflection distance of the dynamic crack increases along the horizontal direction when the dynamic crack and the static crack become coalescenced, end point B of the static crack expands towards the opposite direction, ending in "mutual occlusion" with end point C of the dynamic crack as the displacement and velocity of the latter's expansion increases.
