摘要:
Dynamic shortening of one‐half inch long copper cylinders is achieved by striking them with a hardened steel projectile at high velocities. The average strain rate was about 1200 per second. Energy per unit volume absorbed by the copper is plotted against strain. A true stress‐logarithmic strain curve is computed. This curve is compared with a similar curve derived from high speed tests on copper in tension.
