ABSTRACT
Charpy V-notch (CVN) impact testing, which employs a 10 mm square bar of 55 mm length, is one of the test methods widely used to evaluate the toughness characteristics of a material. Using an instrumented pendulum hammer and precracked and side-grooved specimen, force-time, force-displacement, and energy-displacement curves can be generated for evaluating fracture toughness data in terms of J or KJ.
