Abstract

The response of materials to shock loading has attracted much attention for its applications in high velocity impact, astronautics, explosive working, and defense technology. Scientists are interested in the strain-rate dependence of material performance, especially as it affects dynamic strength, damage, and failure. Since high-strain-rate loading can only be applied for a short time, the available means are: by a plane shock wave produced by plate impact, explosive detonation, gas- or electrically-propelled gun projectiles, and laser-beam irradiation. Other experiments involve freely-expanding rings or exploding cylinders and projectile penetration or plugging of a target. Spall experiments carried out with plane shock waves are most appropriate for fundamental research because two dimensional effects are minimized and loading parameters are easily adjusted over a wide range.
