Sharpe v notch test

WebbThe Charpy impact test method, also known as the Charpy V-notch test, will determine the impact strength and toughness of carbon steel products. It does this by measuring the amount of energy absorbed by a pendulum tool, with more brittle metals breaking more easily than “tougher” metals. This ensures that it’s suitable for the specific ... Webb1 apr. 2000 · This allows for impact tests where the notch is in the base material, in the weld material, or in the HAZ. In the present paper, plane strain analyses of the Charpy V-notch test are carried out for different welded joints, to investigate the ductile–brittle transition in different parts of the weld. In relation to the procedures prescribed in ...
