The impact energy of low-strength metals that do not show a change of fracture mode with temperature, is usually high and insensitive to temperature. For these reasons, impact tests are not widely used for assessing the fracture-resistance of low-strength materials whose fracture modes remain unchanged … Zobacz więcej In materials science, the Charpy impact test, also known as the Charpy V-notch test, is a standardized high strain rate test which determines the amount of energy absorbed by a material during fracture. Absorbed … Zobacz więcej The apparatus consists of a pendulum of known mass and length that is dropped from a known height to impact a notched specimen of … Zobacz więcej The qualitative results of the impact test can be used to determine the ductility of a material.

Impact, by definition, is a large force applied for a very short time, resulting in a sudden transfer of momentum and energy, and its effect is different when the same amount of energy is transferred more gradually. Everyday engineering structures are subjected to it and may develop cracks that, over time, propagate to a point where catastrophic failure would result.
