Abstract:

The use of high-resolution, time-resolved measurements of rear surface velocity in shock loaded 6061-T6 aluminum is discussed as a means of studying spall fracture. The influence of stress pulse shape, material temperature, maximum compressive stress and degree of fracture on free surface motion is presented and correlated with maximum tensile stress at the spall plane. A summary of dynamic properties data equation of state, elastic wave velocity, stress-strain-strain rate behavior, spall threshold and a brief discussion on fracture in metals are also given.
