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. 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.

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

It delivers flexibility – run everything from a simple static ramp, to cyclic waveforms through to complex multi-step, multi-axial tests The highly visual environment with integrated tabular screens, clear menu structures, time-based matrix test preview and configurable live test workspace is designed to be intuitive and instill confidence.

This patented system achieves and maintains a specified test temperature by varying test frequency in response to a specimen temperature input. 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. This standard is not included in any packages.

ASTM D Tension-Tension Fatigue of Polymer Matrix Composite Materials

In this procedure, the test control parameter may be described using engineering strain in the loading direction as a constant amplitude fatigue variable. You can download and open this file to your own computer but DRM asym opening this file adtm another computer, including a networked server. Unfortunately, the fact that specimens generate heat internally means that there is always an offset from the surrounding environment, so temperature rise is not actually controlled even when working in a chamber.

Measures displacement for axial tensile, compression, and cyclic testing Gage lengths from 10 mm to 50 mm 0. Composites and various other materials are prone to significant self-heating effects during cyclic loading, but their performance also shows strong temperature dependence.

ASTM D determines the fatigue behavior of polymer matrix composite materials subjected to tensile cyclic loading. WaveMatrix 2 for Dynamic Testing.

Powered from a single-phase supply it requires no additional utilities for basic machine operation for example, pneumatic air, hydraulics, or water. The user sets the target test temperature and the system then automatically adjusts the live test frequency within user-specified limits to achieve it. Conversely, at high stress levels where each test is several orders of magnitude shorter the frequency must often be reduced to prevent excessive heating, but this has little effect on the overall time for the S-N dataset.

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.

The user sets the target test temperature and the system then automatically adjusts the live test frequency within user-specified limits to achieve it. Replicate tests may be used to obtain a distribution of fatigue life for specific material types, laminate stacking sequences, environments, and loading conditions.
