Metallic materials and welded joints.
The aim of the impact tests in metallic materials is to determine the dynamic energy that the material is able to absorb, due to crystalline flaws interaction, before its breakage. This property is highly influenced by its chemical composition, microstructure and temperature.
The Charpy pendulum test determines the energy needed to breaks a normalized sample with a controlled impact. The sample is machined with a determinate shape and accurate up to 0,020 mm
