DEVICE FOR MEASURING THE DYNAMIC STRESS/STRAIN RESPONSE OF DUCTILE MATERIALS

摘要

Methods and apparatus are disclosed for measuring dynamic tensile stress and/or tensile strain response of materials, such as elastic and/or ductile materials. The apparatus may include a striker bar, a stretcher bar, and a drive assembly configured to propel the striker bar towards the stretcher bar. The apparatus may further include a fixed specimen mount and a movable specimen mount to receive the test sample. The striker bar and stretcher bar of the device provide continuous stress on the test sample and can provide accurate tensile stress/strain measurements.
