The spallation behavior of Armco iron was studied as a function of loading stress and initial pulse duration. The experiments were performed at a planar impact facility equipped with a VISAR interferometric system. By measuring the pull-back signal we determined not only the spall strength but also a macroscopic damage originally introduced by Cochran and Banner. The softly recovered specimens were cross sectioned to correlate the microscopic crack distribution with the VISAR signals.
