Impact

(En anglais seulement) An impact test is used to quantify the resistance of a sample to high-rate loading. It is very useful in the safety study of product. For this test, an indenter is brought into contact with the sample at very high speed and the effect of this impact on the sample is characterized mechanically or visually. This type of test is difficult to realize with most mechanical testers because of the high displacement speed and travel range involved, as well as the high acquisition rate required to measure the resulting load profile at impact. Mechanical damage is the result of material loss through a mechanical action. A mechanical tester can be used with user-specified parameters to induce multi-scale damage.
