Branching of cracks produced in a plate by impact
- 19 Downloads
The problem of crack propagation in the presence of a large number of branching events is considered in the case of a semi-infinite inhomogeneous plate to whose edge an impact load is applied. The theory of random processes is employed. The mean-square distance and the mean-square angular deviation of the cracks from the branching axis are determined; these quantities are convenient for comparison with the experimental data.
