The test specimen is machined to a square or round section, with either onetwo or three notches. The notch is machined to look like a keyhole.
Configuration of test piece supports and anvils.
A test specimen is machined to a 10mm x 10mm full size dn, with either a “V” or “U” notch. Configuration of test piece support.
Izod impact testing machine. The steel casting industry uses this type of specimen more frequently.
Square section, Izod impact test pieces. Charpy impact test pieces. It is tested in the same manner as the “V” and “U” notch.
The impact test is a method for evaluating the toughness and notch sensitivity of engineering materials. Keyhole Impact Test The steel casting industry uses this type of specimen more frequently. The energy absorbed is measured.
The blow is struck on the same face as the notch and at the fixed height above it. 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.
di Specimens can be tested down to cryogenic temperatures. The notched test specimen is broken by the impact of a heavy pendulum or hammer, falling at a predetermined velocity through a fixed distance. 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 test measures the energy absorbed by the fractured specimen.
The specimen is clamped vertically on the anvil with the notch facing the Hammer. It 50115 usually used to test the toughness of metals, but similar tests are used for polymers, ceramics and composites. Charpy Impact Test A test specimen is machined to a 10mm x 10mm full size cross-section, with either a “V” or “U” notch.
Charpy impact testing machine. Izod Impact Test The test specimen is machined to a square or round section, with either onetwo 500115 three notches.
This absorbed energy is a measure of the impact strength of material. Sub-size specimens are used where the material thickness is restricted.
