THE EFFECT OF VELOCITY ON THE DEFORMATION OF MODIFIED CHARPY COPPER SPECIMENS.
Abstract
Using a modified Charpy loading configuration, annealed OFHC copper modified Charpy V-notch specimens were broken with various impact velocities, ranging from 0.00090 to 15384 inches/second. Energy absorption for failure, failure bend angle, and extent of penetration were measured for specimens tested at each velocity station. Both the energy absorption for failure and the final bend angle versus velocity plots depicted three velocity regimes and the presence of two 'critical' velocities. An explanation for the presence of the 'critical' velocities was proposed and documented. (Author)
