Shock Impingement Experiments on Crushable Solids
Abstract
A 2-in. inside diameter shock tube was used to generate strong flat-topped shock waves in argon for impingement against cylindrical specimens of celotex, redwood, and sugar pine up to 6 in. in length. Shock pressures up to 120 atmospheres were induced in the specimens immediately following impingement. Piezoelectric crystal pressure sensors were used to record pressure-time histories in the gas upstream of the gas-solid interface. A method of obtaining points on the shock pressure-specific volume curve (the Hugoniot) for each solid from the experimental data is given in the present report. The results for each material are presented graphically, and are compared with isothermal confined static compression data. Rather large volume changes are evidenced in shock at pressures in the neighborhood of the crushing strength for each material. The crushing strength of celotex in shock appears to be well above its confined static crushing strength, and the crushing strengths in shock of redwood and sugar pine appear to be somewhat below the corresponding static crushing strengths.
