Standard E 23, ―Standard Test Methods for Notched Bar Impact Testing of Metallic Materials‖. In 1901, a French researcher named Charpy published his work—the second publication in the world on pendulum machine testing—on notched bar pendulum impact tests [2]. Charpy’s tests used a pendulum impact machine based on the design developed .
The objective of the Charpy impact test to ISO 148-1 is the determination of the impact energy and determination of the impact strength of a metal. The test indicates whether the metal is tough or brittle. In addition, the tough/brittle transition can be determined based on the temperature. Impact strength is a material characteristic value.In this paper, a three-dimensional Finite Element (FE) model was performed to simulate the impact test ofnormalized carbon steel and aluminum specimens. The model specifications were developed according to ASTM E-23 standard requirements. Also the established FE model took into account all sources of non-linearity such as geometric, material and contact nonlinearities. . The Charpy impact test (Charpy V-notch test) is used to measure the toughness of materials under impact load at different temperatures! Test setup and test procedure. In the Charpy impact test, a notched specimen is abruptly subjected to bending stress. The specimen is usually 55 mm long and has a square cross-section with an edge length of 10 mm.This is ironic for a 100-year-old test because, as discussed in this paper, it can be reasonably argued that percent shear is the most fundamental and physically meaningful of the three Charpy parameters for brittle fracture characterization. . In a Charpy impact test, three key measurements are typically made: total absorbed energy, lateral .
