WaveMatrix Specimen Self-Heating Control Increase the throughput and consistency of your composites and polymers testing by optimizing the test frequency with the Specimen Self-Heating Control.

Aztm Self-Heating Control can significantly reduce this, while providing previously unachievable confidence in test temperature. As the voice of the U. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server.

This has traditionally led to fatigue testing at very low frequencies to minimize specimen heating and the resultant degradation in mechanical properties.

ASTM D3479 Tension-Tension Fatigue of Polymer Matrix Composite Materials

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

By means of our testing expertise and modular product design, we will help find the solution that is right for you.

The primary test result is the fatigue life of the test specimen under a specific loading and environmental condition. Powered from a single-phase supply it requires no additional utilities for basic machine operation for example, pneumatic air, hydraulics, or water. Replicate tests may be used to obtain a distribution of fatigue life for specific material types, laminate stacking sequences, environments, and loading conditions. If the document is revised or amended, you will be notified by email.

Static and fatigue forces up to 25 kN 5, lbf Frequency ratings up to Hz Servohydraulic Small, portable footprint. WaveMatrix 2 for Dynamic Testing. Proceed to Checkout Continue Shopping. Increase the throughput and consistency of your composites and polymers testing by optimizing the test frequency with the Specimen Self-Heating Control. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

The composite material forms are limited to continuous-fiber or discontinuous-fiber reinforced composites for which the elastic properties are specially orthotropic with respect to the test direction. The composite material forms are limited to continuous-fiber or discontinuous-fiber reinforced composites for which the elastic properties are specially orthotropic with respect to the test direction.

In this procedure, the test control parameter may be described using engineering strain in the loading direction as a constant amplitude fatigue variable. 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.

We are confident that we have what you are looking for. Temperature has a major effect on results since the performance of these materials is far more temperature sensitive than that of metals.

The user sets the target test temperature and the system then automatically adjusts the live test frequency within user-specified limits to achieve it.

Subscription pricing is determined by: Conversely, at high stress levels where each test is several orders of magnitude shorter the frequency must often be reduced to prevent excessive heating, d349 this has little effect on the overall time for the S-N dataset.

Increase the throughput and consistency of your composites and polymers testing by optimizing the test frequency with the Specimen Self-Heating Control.

axtm 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.

Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. This information can be useful in the asstm of fatigue behavior of composite structures under spectrum loading conditions, but is not covered in this test method. In this procedure, the test control parameter may be described using either engineering stress or applied load as a constant amplitude fatigue variable.

Combining values from the two systems may result in non-conformance with the standard.
