specimen fracture:
V-shaped notch
Not broken with W = 13.6 J
K = 18 J/mm2
W = m g H
Test S235JR
specimen fracture:
V-shaped notch
W = 4 J
K = 6.6 J/mm2
Test Al 2007
Test characteristics
- check the suitability of the test tube;
- verification of zeroing of the Charpy pendulum ;
- positioning of the specimen;
- execution of the test in compliance with the safety standards;
- data collection and analysis of results:
Work to brake the specimen:
W = ( m·g·H ) – ( m·g·h)m = the pendulum massg = gravitational accelerationThe impact toughness:
K = W / SoS0 : cross-section area of the specimen at the notch.
Test procedure
- U-shaped notch, 5 mm deep
- V-shaped one, 2 mm deep
- non-ferrous materials - Mesnager tube V-shaped notch, 2 mm deep
Test specimen
- Sharpy test determines the impact resistance of materials.
- Destructive test
- Charpy pendulum used
