Fracture behavior of brittle circular rings subjected to concentrated impulsive loading
- 40 Downloads
The influence of impact velocity and ring geometry in the fracture patterns produced by in-plane concentrated impulsive loading on brittle circular rings has been studied both experimentally and theoretically. The experiments were performed by impacting circular rings made of plaster with a steel plate. The fracture behavior was photographed by a camera with a flash, and the crack-initiation time was measured using a memoriscope. The fracture behavior is explained using dynamic photoelasticity and the theory of flexural motion of a circular ring. With the addition of an impact-fracture criterion to this theory, the fracture patterns of brittle circular rings are predicted.
