Abstract

Aluminum tubes artificially flawed by milling to form spots of thinned-down wall were subjected at room temperature to internal water pressure, which was gradually increased until rupture at the flaw spot. The progress of crack opening at the flaw spot was observed by stroboscopy, using a drum camera with strobo-flash triggered by platinum wire stretched in front of the flaw spot. The pressure inside the tube near the flaw was monitored by semiconductor transducers. The simple trigger arrangement proved to function very satisfactorily. The time required for a crack to open to 90% of its final dimension was several tenths of a millisecond for all cases where the artificial flaw was of flat form and several milliseconds for all "pit" flaws.
