Software Add-on Limits Specimen Self-heating Under Dynamic Loads
Instron announced the release of the Specimen Self-Heating Control (SSHC) add-on to the versatile Instron WaveMatrix Software package for dynamic and fatigue testing of polymers and composites. It maintains specimen temperature within a tight band and can save time, cost, and energy in the QC test lab, as well as in the development and optimization of composite formulations.
Polymers and composites show a pronounced self-heating effect during cyclic loading and a strong temperature performance correlation, so fatigue testing is traditionally conducted at rather low frequencies. The SSHC add-on uses the difference between the specimen’s continuously recorded temperature and a pre-specified temperature target to maximize the testing frequency in a closed loop.
