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.enArmco-EisenArmco irongrowth and coalescence of cracksnucleationNukleationplanar impact testPlanarer ImpakttestreflectionReflektionRißSchockwelleshock waveSpallationtransmissionVereinigungVISAR interferometryVISAR interferometryWachstum620conference paper
