Charpy and Izod Impact Testing
Commonly used on non metallic materials, Charpy and Izod testing use a swinging pendulum to determine impact resistance.
Using a swinging hammer to strike a notched sample from a known distance, Charpy and Izod testing measure how much energy is required to cause failure. In addition to determining energy absorption and impact resistance, these methods can provide insight into thefracture toughness properties of polymers, elastomers and composites.
Gardner Impact Testing
Used to determine the impact resistance of supported materials, Gardner impact testing (also known as falling dart impact) uses a fixed weight falling from various heights to determine the mean failure energy of a material type. Testing is often performed to validate manufacturing processes or characterize material properties.
