Impact resistance tests

Impact resistance tests are tests that characterize the material’s resistance to cracking under dynamic load. Performed to determine the effect of load speed and strain on the mechanical properties of materials, they define features impossible to determine by static tests.

Impact resistance tests – testing capabilities

To perform impact resistance tests, devices are used that allow the application of a large force in a short time, the so-called impact hammers. In addition to the standard Charpy hammer, we also have its instrumented version, thanks to which it is possible to determine not only the impact work, which is a measure of the material’s resistance to cracking, but also to determine the characteristics of the destructive force as a function of time.

We have special digitally controlled chambers, designed to perform tests on samples with reduced or elevated temperature – a cooling chamber (samples cooled to -180°C) and a heating chamber (tests up to 300°C).

We test both metallic and composite materials.
