Zusammenfassung:	DEVICE FOR MEASURING THE DYNAMIC STRESS/STRAIN RESPONSE OF DUCTILE MATERIALS A method and apparatus for measuring a dynamic tensile stress and/or tensile strain response of a material such as an elastic material and/or a ductile material. The apparatus may include a striker bar (104), a stretcher bar (106), and a drive assembly (114) configured to propel the striker bar (104) toward the stretcher bar (106). The apparatus may further include a stationary specimen mount (132) and a movable specimen mount (134) that receive a test sample. The striker bar (104) and the stretcher bar (106) of the apparatus may provide a continuous stress on the test sample and an accurate tensile stress/strain measurement. (00 co6 (N(D (00 co. !PO
