Italian researchers based at the Department of Mechanics in the Politecnico di Milano have selected HBM’s GEN7t (successor GEN7tA) high-speed equipment to improve the reliability and accuracy of data acquisition on Charpy tests.
Charpy impact machines are used in material testing to determine whether a specimen is brittle or ductile. The test is a standardized high strain-rate test to determine the energy absorbed by a material during fracture as a measure of the sample’s toughness.
The test comprises a pendulum swung at a notched sample of material and the energy transferred to the material can be calculated before and after the material has fractured.
