The deformation and fractures produced by internal explosive loading in thick cylinders are different to those caused by a gradually increasing load.
Graphs showing the variation in circumferential strain for cylinders of different lengths and diameters are presented and the fractures discussed. The similarity between the fracturing of perspex and mild-steel cylinders is also shown.
