    Izod impact strength test. Izod impact testing is an ASTM standard method of determining the impact resistance of materials. A pivoting arm is raised to a specific height (constant potential energy) and then released.The arm swings down hitting a notched sample, breaking the specimen. The energy absorbed by the sample is calculated from the height the arm swings to after hitting the sample.

    Impact (mechanics) Or, another way to look at it is that materials actually are more brittle on short time scales than on long time scales: this is related to time-temperature superposition . Impact resistance decreases with an increase in the modulus of elasticity, which means that stiffer materials will have less impact resistance.
