Computer Modeling of Crack Propagation in Biaxially-Stressed Glass Disks

Abstract
A computer program was written to model the propagation of two-dimensional traveling cracks in a biaxially-stressed glass disk. This was accomplished by using a combination of known fractographic equations and empirical observations with generic algorithms for generating fractals. Inputs include material property data, fracture load, disk size, and the sizes of the load-bearing rings. The outputs include fracture stress, initial crack size before branching, and a prediction of the expected number of radial cracks. A typical image of a fractured disk with the input conditions is also produced. The image incorporates empirically-determined randomness and a degree of crack curvature dependent on the stress state. The program is user-friendly, and may be easily adapted for other materials and conditions.Proceedings Title
