resistance to impact

To obtain the resistance curve of crack growth of an elastic-plastic material, a test for dynamic crack initiation and arrestment is carried out on a self-designed bar-bar tensile impact apparatus by using larger diameter short specimens with deep circumferential notches and larger ligament diameters.
