dynamic materials testing
Dynamic material testing checks metals under impact or cyclic loads to assess their fatigue and impact toughness. These methods simulate realistic operating conditions.
Physico-chemical mechanism of action
Dynamic material testing refers to test methods where metals are tested under impact or cyclic loading. These tests can be carried out by mechanical blows, pressure waves, or other impact phenomena.
Metallurgical relevance & risks in welding
Dynamic material testing is crucial for assessing the fatigue and impact toughness of metals. Incorrect test conditions can lead to inaccurate results, which in turn can lead to faulty material selection or use in construction.
Workshop practice & instructions
For dynamic material testing, special equipment such as impact testing machines or pressure wave generators must be used. The test conditions, including the number and intensity of impacts, must be precisely defined. An example is the Charpy test, where a metal specimen is tested under a sudden impact. The results are measured in joules (J), indicating the energy absorption of the material.
