Charpy Impact testing is used in studying material toughness and most importantly it indicates a material ability to absorb energy and plastically deform without fracturing. In this study, three stainless steel specimens at different . Abstract. 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. In the material testing laboratory, a Charpy impact test was performed on three different types (hot,cold,and steel alloy)of steels testing each variety at four different temperatures (32°C(RT), 100°C,0°C and -22°C ).

specimen to the deforming or breaking specimen is equated to the "impact energy." The Charpy impact test uses a standard Charpy impact machine to evaluate this impact energy. The machine consists of a rigid specimen holder and a swinging pendulum hammer for striking the impact blow to a v-notched specimen as shown in Figs. 1 and 2.

Abstract. This review provides an overview of experimental impact testing and numerical impact simulations for composite materials in terms of a complementary combination of both techniques. . Other low-velocity impact testing methods include Charpy and Izod, which use a pendulum hammer to strike and fracture a test specimen from a fixed .In a Charpy impact test, three key measurements are typically made: total absorbed energy, lateral expansion, and percent shear fracture area. At present, the measurements of absorbed energy and lateral expansion are quantitative and well defined, but the methods used by most laboratories in the measurement of percent shear are qualitative at best.

Although two standardized tests, the Charpy and Izod, were designed and used extensively to measure the impact energy, Charpy v-notched impact tests are more common in practice. The apparatus for performing impact tests is illustrated schematically in Figure-I. The load is applied as an impact blow from a weighted pendulum hammer that is released The Instrumented Charpy impact test is a promising method for determining a material’s impact response. Stainless steel has higher impact energy absorption capacity, high tensile, and yield .As for the impact price test specimen is different because there are several factors that cause differences in the size of the test specimen, the weight of the pendulum, the length of the pendulum arm, and the difference from the initial angle of the pendulum. Chaerul Umam Wardani et al in 2009, analyzed the impact testing of the Izod and Charpy
