The results of an experimental investigation designed to determine the effect of damage created by hydrostatic tensile loading on the properties of copper are reported. Three metallurgical conditions of half‐hard OFHC copper were investigated; as worked; annealed 2hr at 400°C (∼40 micron grain diameter); and annealed 2hr at 800°C (∼80 micron grain diameter). Mechanical property characterization included uniaxial compression tests. High rate plasticity and damage was introduced by Taylor and rod‐on‐rod impact tests. The damage from the high rate experiments was characterized using optical and scanning electron microscopy. Quasi‐static compression specimens machined from recovered high rate samples were tested to determine the influence of damage on the mechanical response of the material. The compression test results will be discussed in relationship to the starting microstructure and the extent of damaged introduced into the material.
