ASTM E2248 – 18: Standard Test Method for Impact Testing of Miniaturized Charpy V-notch Specimens.; Ductile to brittle transition in impact testing. Carbon steel and low alloy steel are characterized by the fact that the fracture behavior changes as the temperature drops and the fracture type changes from ductility to brittleness. An Izod impact testing apparatus — which is essentially identical to a Charpy impact testing machine — is used to determine Izod impact strength. The primary differences between the Izod and Charpy impact tests are the size of the test specimen, how it is restrained, and which side is struck by the pendulum hammer.

Practical Applications; Introduction. One common high-strain-rate test is the Charpy impact test. It calculates the energy a material absorbs during fracture. The amount of energy absorbed indicates how tough the material is. It is a tool for researching the ductile-brittle transition that is dependent on temperature.The Charpy impact specimens of each material are immersed in a bath for 10 minu tes to reach thermal equilibrium at five separate temperatures ranging from 110oF (-79oC) to 212-oF (100oC). The specimens are quickly transferred to the Charpy testing machine, fractured, and the impact energy is measured. After
Impact test. Measures the ability of a material to absorb a sudden application of a load without breaking. The Charpy test is a commonly used impact test. Lateral expansion. The lateral change in dimension of a Charpy impact specimen due to fracture. The dimension measured is the width opposite the v-notch (see Fig. 1-3). The Charpy impact test, just like any impact testing method, determines the toughness of materials by measuring the amount of energy absorbed by a specimen as it fractures while being struck by a .

Fracture toughness testing standards such as ASTM E1820 or ASTM E 1921 ISO 12350 are seldom used in practice. Estimates of K Ic or J Ic by empirical correlations with classical Charpy impact tests are much more popular and often preferred. The reasons for this unsatisfying situation is that the standard procedures of fracture toughness testing are much . Test criteria for Charpy V-notch impact testing usually involve (i) a minimum impact energy value, (ii) shear appearance of fractured test bars expressed in percent, and (iii) lateral expansion. For steels, the minimum acceptable values generally specified for these three evaluation methods are 20 J, 50 % shear, and 1.3 mm respectively.
