This device measures the resilience of materials to high-velocity impacts. A notched specimen is held vertically as a swinging pendulum strikes it. The energy absorbed during fracture, indicated by the pendulum’s swing height after impact, quantifies impact strength. This method finds common application in evaluating plastics, composites, and some metals.
Impact resistance is a crucial material property, especially in applications subject to sudden loads or shocks. Understanding this characteristic helps ensure product safety and durability, preventing premature failure in critical components. Historically developed to test the durability of insulation materials, this technique evolved to become a standardized assessment for a wider range of substances, contributing significantly to material science and engineering advancements.
