Shock Compression of Tantalum.
Abstract
The free-surface velocity of a shock-loaded 3.73-mm-thick tantalum disk has been measured with a capacitor gauge. Stress reverberations were produced in the tantalum disk by impacting it with a 2.65-mm-thick alpha titanium disk at a velocity of 0.111 km/s in a gas gun. An initial shock compressive stress slightly larger than the measured 2.1-GPa Hugoniot elastic limit was produced in the tantalum. The shape of the free-surface-velocity profile suggested that spall fracture did not occur in the specimen disk at this stress level. This result was verified by examining the recovered and sectioned disk. (Author)
