Charpy Testing machine perform test on metals as well as on polymers, ceramics as well as composites and is commonly used for evaluating relative toughness/impact toughness of materials. This makes the test useful in quality control applications.
As a fast & economical test, it is used more as comparative test rather than definitive test where the Charpy test specimens normally measure 55x10x10mm. Further, these have notch that is machined across one of larger faces.
The notches may be in form of:
- U-notch/keyhole notch
