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.
The Charpy impact test, also known as the Charpy V-notch test, is a high strain-rate test that involves striking a standard notched specimen with a controlled weight pendulum swung from a set height. The impact test helps measure the amount . The Izod impact test fixes one end of a notched specimen in a cantilever position by means of a vice. A striker on the arm of a pendulum or similar energy carrier then strikes the specimen. The energy absorbed by the specimen in the breaking process is known as the breaking energy. The breaking energy can be converted into an indication of a .

Impact energy characterizes the ability of a structure to consume energy through deformation and fracture under impact load. The impact energy A k, a value measured by the Charpy impact test, is mainly used to control the quality of metallurgical and thermal processing products and determine the ductile-brittle transition temperature of .A Charpy impact test can be done to determine the ductility, toughness, and ductile-brittle transition temperature of plastics. Likewise, it can be done to find out the sensitivity of notched plastic specimens. The notches used for Charpy impact testing are V-notch and U-notch while the notch used for Izod impact testing is only V-notch. To successfully perform a Charpy V-notch impact test, the following steps must be followed for accurate results: 1. Notch test specimens. The standard size of a specimen for Charpy impact testing is 10 mm × 10 mm × 55 mm. A 2mm deep notch with an angle of 45° and a tip radius of 0.25mm is then machined into one face of the bar.
Impact Strength Test. Impact strength test was performed according to ISO standard 1567:1999/Amd.1:2003(E) . A type V notch was cut in the middle of each specimen using a milling machine (Model FNGJ32, INTOS Ltd., Czech Republic) and a universal milling tool (Model 1322, 45° double angle; Sandvik Coromant, Sweden).Scope- This standard specifies the Charpy impact ( V-notch ) method for determining impact strength of the metallic material. 2. Principle - This test consists in breaking by one blow from a swinging pendulum, under conditions defined hereafter, a test piece V-notched in the middle and resting on two supports. U- and V-notched specimens for impact testing require precision and compliance with standards. It starts with selecting the appropriate material, taking into account its properties and the specific parameters of the test standards. The material is then cut to exact dimensions using advanced tools like CNC machines and precision cutters.
