Increase the throughput and consistency of your composites and polymers testing by optimizing the test frequency with the Specimen
Self-Heating Control. This powerful add-on is specific for WaveMatrix™ Software.
Composites and various other materials are prone to significant self-heating effects during cyclic loading, but their performance also shows
strong temperature dependence. This has traditionally led to fatigue testing at very low frequencies to minimize specimen heating and the
resultant degradation in mechanical properties. A test run for a single S/N dataset could mean weeks of machine time.
Specimen Self-Heating Control can significantly reduce this, while providing previously unachievable confidence in test temperature. This
patented system achieves and maintains a specified test temperature by varying test frequency in response to a specimen
temperature input.
This means that for lower loading, where very large numbers of cycles-to-failure are expected, the system can be allowed to run at
significantly higher frequency, which greatly reduces the test duration. Meanwhile at high loading, consistent specimen temperature is
maintained even in the latter stages of the test, during which self-heating effects increase dramatically resulting in run-away specimen
temperature with fixed frequency tests.
For structural composites, a 5°C shift in temperature will have a greater effect than a two-fold change in test frequency, so the benefit of
tightly controlled test temperature greatly outweighs moderate variation in test frequency.
