The specimen is clamped vertically on the anvil with the notch facing the Hammer. The Izod impact test is a dynamic test in which a test piece V-notched test piece, gripped vertically, is broken by a single blow of a freely swinging pendulum Fig.

The steel casting industry uses this type of specimen more frequently. Keyhole Impact Test The steel casting industry uses this type of specimen more frequently.

The energy absorbed is measured. Configuration of test piece support.

The notch is machined to look like a keyhole. Izod Impact Test The test specimen is machined to a square or round section, with either onetwo or three notches. Sub-size specimens are used where the material thickness is restricted. Izod impact dkn machine.

Charpy impact test pieces. Square section, Izod impact test pieces. The impact dib is a method for evaluating the toughness and notch sensitivity of engineering materials.

The test measures the energy absorbed by the fractured specimen. Configuration of test piece supports and anvils.

A test specimen is machined to a 10mm x 10mm full size cross-section, with either a “V” or “U” notch. The blow is struck on the same face as the notch and at the fixed height above it.

Charpy Impact Test A test specimen is machined to a 10mm x 10mm full size cross-section, with either a “V” or “U” notch. This absorbed energy is a measure of the impact strength of material.

The notched test specimen is broken by the impact dib a heavy pendulum or hammer, falling at a predetermined velocity through a fixed distance. The Charpy impact test is a dynamic test in which a test piece U-notched or V-notched in the middle and supported at each end, is broken by a single blow of a freely swinging pendulum Fig.

It is usually used to test the toughness of metals, but similar tests are used for polymers, ceramics and composites. Charpy impact testing machine.

Specimens can be tested down to cryogenic temperatures. It is tested in the same manner as the “V” and “U” notch.

The test specimen is machined to a square or round section, with either onetwo or three notches.
