Various specimen sizes of an unreinforced polymer, Hercules 3501 -6 thermosetting epoxy, were subjected to a tensile test. The general specimen geometry was a rectangular dog-bone shape with constant gauge length, but with each specimen size having a different crosssectional area. These cross-...
Polymer mechanical testing subjects the test specimen to different degrees and types of mechanical stress to understand how it will perform under extreme conditions. Element’s capabilities for mechanical testing include, but are not limited to: ...
Each specimen is expanded repeatedly at various strains at 300 cycles per minute to failure. Our extensive sample preparation facilities at our rubber testing lab can test a huge variety of materials and product forms and are equipped with a CNC machine, on-site moulding, and slitting and buffin...
Ultimate Open Hole (notched) Tensile Strength (OHT) is reported in Mpa (psi) and is equal to the maximum force carried by the test specimen prior to failure N (lbf) divided by the gross cross sectional area mm2 (in 2). The area is calculated disregarding the hole and as outlined in ...
specimens with either run-arrest or stable crack extension. For reasons of comparability, top surface analysis (TSA), as recently reported, was also carried out. Following this approach, the crack propagation was tracked applying DIC to the top specimen surface. The methods developed showed a ...
RLMNPs-based rectangular specimens were printed to test photothermal effects. Samples were irradiated with 808 nm NIR laser at different laser power densities (0, 0.1, 0.3, and 0.5 w/cm2) for 3 min. The maximum temperature of the specimen was monitored in real-time by the infrared ther...
Some of the aspects of the test validity are related to the specimen manufacture, particularly the quality of the notches. Two sets of specimens have been prepared, the first one sharpened by the femtosecond laser ablation technique, and the second one sharpened by the classical razor blade ...
The specimen size was 20 mm × 4 mm × 0.2 mm. The storage modulus and the loss factor were measured from ‒80 to 30 °C. The Fourier Transform Infrared (FT-IR, NICOLET-5700) spectroscopy (400–4000 cm−1, resolution 2 cm−1) was carried out at...

The size of the specimen was 24 × 5 × 0.3 mm3. The measurement was performed using tension mode from 40 to 190 °C at 5 °C/min with a static loading of 49 mN. A constant N2 flow rate of 200 mL/min was maintained through the TMA instrument during the ...
