The Charpy test involves striking a suitable test piece with a striker mounted at the end of a pendulum. The test piece is fixed in place at both ends, and the striker impacts the test piece immediately behind a machined notch, causing it to sever.

The specimens (five in total) are machined to a small notched piece and placed into the Charpy tester. Then the arm of the striker is released, and the striker falls in a pendulum arc, striking and recording the amount of energy absorbed during the fracture.

More Information

The Charpy impact test, or the Charpy v-notch test, is a high strain-rate test that determines the amount of energy absorbed by a material during fracture. This absorbed energy is a measure of a given material’s fracture toughness. This test is performed on a Charpy impact test machine. The materials tested are usually parent material, weld material, and interface material.
