AI Technical Summary
Existing tensile testing systems suffer from wall slippage and measurement data distortion when performing large deformation tests on soft elastomers such as rubber and hydrogels. They are unable to accurately acquire even-order harmonic signals, resulting in inaccurate material characterization.
A double-rod floating fixture design with a ring-shaped polymer elastomer sample and floating contact was adopted. Combined with vacuum environment and spectrum analysis, wall slippage was eliminated and even-order harmonic signals were extracted.
It improves measurement accuracy and signal-to-noise ratio, accurately acquires even-order harmonic signals, provides a new dimension for high-sensitivity material characterization, and has system self-testing capabilities.
