What are impact tests?

These are tests that provide information on the behaviour of materials or components subjected to impulsive loading (shocks, explosions).These tests can be performed at different speeds, different energy and by evaluating the different temperature on the characteristics of components and materials. These tests can be performed with two types of machinery: pendulums and drop towers. STEP Lab specialises in realising and performing tests on drop towers due to their advantage in terms of flexibility of use.

Punching tests on plates

Punch tests are of particular interest for moulding materials. This type of test imposes a multi-axial stress state on a thin plate by applying a high deformation rate. The results are a force-displacement or force-time diagram and point data on bending characteristics and maximum force. Punch plate tests are defined in ISO 6603-2 and ASTM D3763. ISO 7765-2 is a variation of the standard and is used for tests on films.

Impact tests with high-speed testing machines

HTM high-speed testing machines can be widely used for testing plastics. They are characterised by high test speeds and wide force ranges and can be used flexibly in tensile and compression tests. In addition, they can be equipped with a climatic chamber to perform tests at different temperatures.
