Abstract of DEUTSCH-NIEDERLÄNDISCHE ELASTISCHE BEZIEHUNGEN     2016

Dynamic mechanical testing ; specimen self heating control an efficient way of dynamic mechanical lifetime prediction of elastomers ?

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.
