As a contribution to the problem of the strength of glass pipes and containers subjected to thermal shock loading, the effect of shock cooling on glass cylinders was investigated, whose inner surfaces contained defined surface cracks. A theoretical fracture mechanics analysis of continuous axial and circumferential cracks of constant depth enabled predictions to be made for a given shock magnitude of the minimum crack depth for crack extension to occur, of the times to fracture and their dependence on crack depth, and of the development and extent of crack propagation in the cylinders under consideration. These predictions could be largely confirmed albeit qualitatively by the results of experiments on glass cylinders containing small, artificially-induced precracks. The extent, direction and speed of crack growth were determined by subsequent analysis of either natural or ultrasonically induced fracture surface markings.
