    en.wikipedia.org/wiki/Izod_impact_strength_test

    Izod impact tester in Blists Hill Victorian Town. The Izod impact strength test 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.

  3. Charpy impact test - Wikipedia

    en.wikipedia.org/wiki/Charpy_impact_test

    A vintage impact test machine. Yellow cage on the left is meant to prevent accidents during pendulum swing, pendulum is seen at rest at the bottom The apparatus consists of a pendulum of known mass and length that is dropped from a known height to impact a notched specimen of material.

  4. Notch (engineering) - Wikipedia

    The most common is the Charpy impact test, which uses a pendulum hammer (striker) to strike a horizontal notched specimen. The height of its subsequent swing-through is used to determine the energy absorbed during fracture. The Izod impact strength test uses a circular notched vertical specimen in a cantilever configuration. Charpy testing is ...

    Often measured with the Izod impact strength test or Charpy impact test, both of which measure the impact energy required to fracture a sample. Volume, modulus of elasticity, distribution of forces, and yield strength affect the impact strength of a material. In order for a material or object to have a high impact strength, the stresses must be ...
