Theoretical And Experimental Study Of Explosive Closures Of 6061-0 Aluminum Pipes, Lyle E. Edwards
Theoretical And Experimental Study Of Explosive Closures Of 6061-0 Aluminum Pipes, Lyle E. Edwards
Mechanical Engineering ETDs
This thesis examines the use of explosives to collapse metal pipes from an applications point-of-view. A particular system is studied, both theoretically and experimentally, in order to facilitate the future design of such closures with the least possible physical testing. The calculations are based on a rigid-perfectly plastic model of the observed deformations of the tubes, and on various assumed am derived properties of the metal and sheet explosives under the dynamic conditions of closure. A computer program has been devised which simulates the actual motion of a pipe during collapse. Experimental work involved actual test firing of aluminum cylinders …

A new procedure is described for using the moiré-fringe technique to measure strains in structural materials at temperatures exceeding 1300 °C. The principal factor found to be necessary for successful viewing of moiré patterns at extremely high temperatures is the use of reflected laser light for viewing the strained grid on the material. This factor is extensively discussed and experiments are described in which strain measurements were successfully made on graphite specimens at elevated temperatures. It is concluded that the techniques described constitute a more feasible method of measuring strains at higher temperatures than is possible by any other known …
