Have a question about conducting the test for this standard? WaveMatrix Specimen Self-Heating Control Increase the throughput and consistency of your composites and aatm testing by optimizing the test frequency with the Specimen Self-Heating Control.

Replicate tests may be used to obtain a distribution of fatigue life for specific material types, laminate stacking sequences, environments, and loading conditions. This patented system achieves and maintains a specified test temperature by varying test frequency in response to a specimen temperature input.

Powered from a single-phase supply it requires no additional utilities for basic machine operation for example, pneumatic air, hydraulics, or water. Standards Subsctiption may be the perfect solution. In recent years, composites fatigue testing has rapidly moved from a research interest to a critical commercial requirement, but the cost – in terms of machine time – remains a asmt challenge to commercial testing The wind energy industry has led this demand, but aerospace and automotive sectors are defining their own needs in this area and fatigue performance is expected to become an additional qualification requirement for their composite aetm and assemblies.

This test method is limited to unnotched test specimens subjected to constant amplitude uniaxial in-plane loading where the loading is defined in terms of a test control parameter. Standard practice demands a single low frequency typically 3 to 5 Hz for all tests in order to avoid overheating, but that means very long and expensive test schedules.

Description Literature Contact Us In recent years, composites fatigue testing has rapidly moved from a research interest to a critical commercial requirement, but the cost – in terms of machine time – remains a significant challenge to commercial testing The wind energy industry has led this demand, but aerospace and automotive sectors are defining their own needs in this area and fatigue performance is expected to become an additional qualification requirement for their composite materials and assemblies.

Already Subscribed to this document. Specimen Self-Heating Control can significantly reduce this, while providing previously unachievable confidence in test temperature. This means that at low stress levels, where each specimen survives millions of cycles, the frequency can be increased to greatly reduce the test time. Subscription pricing is determined by: We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications.
