The notch acts as a stress concentrator and simulates what occurs if a part is scratched or cut in a specific application, making it easier to break the product. How did you discover Impact Solutions? Material breaks with large plastic deformation (little energy absorption) are known as ductile material. This test involves an arm held at a specific height, which when released hits the sample and breaks it. This test determines the rate and magnitude of consolidation of a soil specimen restrained laterally and subjected to a number of successive increments of vertical loads. Testing was conducted on an Impact Tester-Izod Charpy Tension Impact (Testing Machines Inc; Amityville, New York). brittle fracture when tested in a notched-impact test. At 20 wt% graphite/graphene loading in PEEK, the notched Izod impact strength is 324% greater than the neat polymer, which is an obvious enhancement that is hard to neglect.
