High strain rate test machine
WebThe Charpy impact test, also known as the Charpy V-notch test, is a standardized high strain-rate test that determines the amount of energy absorbed by a material during fracture. This absorbed energy is a measure of a given material’s notch toughness and acts as a tool to study temperature-dependent ductile–brittle transition. WebThe stroke velocity is selected by multiplying the target strain rate by the parallel length of the specimens according to ISO 26203-2:2011 [32], which is the control parameter of the test systems.
