Abstract
The approach to the ultimate strength of metals is determined experimentall y. The ultimate strength of metals was calculated using a realistic wide-ra nge equation of state. The strength of metals was measured using shock wave s created in aluminum and copper foils with a short- (20-100 ps) pulse high -power laser. The strength of the materials was determined from the free-su rface-velocity time history, which was measured with an optically recording velocity interferometer system. The strain rates in these experiments were in the range (1.5-5)x10(8) s(-1). (C) 2000 American Institute of Physics. [S0003-6951(00)03112-0].
