Sharpe v notch test
Did you know?
WebbThe Charpy V-notch-CVN impact test also known as the Charpy V- notch test, is a standard test used to measure the impact energy (also referred to as notch toughness) absorbed by a material during fracture. The notch provides a point of stress concentration within the specimen and improves the reproducibility of the results. Webb1 Answer Sorted by: 2 The point is to promote the condition of brittle fracture. The notch here acts as a stress riser and favours the crack propagation. This test is designed for …
