Abstract

In order to study the crack growth and crack arrest law of the brittle materials, a large-sized trapezoidal opening crack with arc bottom (TOCAB) configuration specimen was proposed. The impact tests were carried out on the TOCAB specimens with radians of 0°, 60°, 90° and 120° under the drop hammer impact device. The crack growth speed was obtained by using the distance between the two resistance wires divided by the break time of the resistance wire of the crack propagation gauge, and crack propagation gauge (CPG) was used to monitor the crack initiation time and expansion time. The crack growth behavior of the TOCAB specimen was numerically simulated by using the finite difference software AUTODYN. And the crack growth process and the crack arrest law were numerically studied. The critical dynamic stress intensity factor of the moving crack was calculated based on the experimental-numerical method and the finite element software ABAQUS. Both experimental and numerical results show that the three arc-bottom specimens have a crack-stopping effect on the moving crack, andthe TOCAB configuration specimen is suitable for studying the crack arrest problem. And the crack growth path obtained in the numerical calculation is basically consistent with the experimental results, which verifies the validity of the numerical model. And the critical dynamic stress intensity factor at the time of crack initiation and crack arrest is greater than that at the time of the crack growth.
