Expert Commentary
Dynamic Energy Transfer: For sub-size specimens (5mm), centering within the anvil is critical; even a 0.5mm offset can cause a shearing strike rather than a clean fracture, leading to artificially high energy readings. The fixture must utilize specialized spacers to ensure the striker hits the exact center of the notch. From an engineer’s perspective, the hammer velocity must be strictly maintained; if the friction in the pendulum pivot exceeds standard limits, the recorded energy absorption is no longer a true material property but a machine artifact.
