SpletThe phenomenon, named for rubber scientist Leonard Mullins, working at the Tun Abdul Razak Research Centre in Hertford, can be idealized for many purposes as an instantaneous and irreversible softening of the stress–strain curve that occurs whenever the load increases beyond its prior all-time maximum value. Splet16. nov. 2024 · As longitudinal power increased from 40% to 70% to 100%, the average time to groove the lens decreased. At a 40% power setting, the average time was 19.83 seconds, at 70% the average time was 15.25 seconds, and at 100% the average time was 14.92 seconds. Increasing power from 40% to 70% revealed an increase in efficiency of 28% ( P …

SpletThe Payne effect was calculated as the difference between the storage modulus, G’ at 0.56% and G’ at 100.04% strain. The Payne effect after cure was measured after vulcanization in the RPA 2000 at 150ºC for 10 minutes and subsequent cooling to 100ºC, making use of the same strain sweep conditions. SpletThe Payne Effect testing measures the stress-strain behavior of tested materials. Physically, the Payne effect can be attributed to deformation-induced changes in a material’s microstructure, i.e. to breakage and recovery of weak physical bonds linking adjacent filler clusters.

In carbon black or silica filled rubber we measure a high dynamic modulus at low strains (< 1%) which decreases at higher strains (> 10%). The reason for this phenomenon is the formation of a network formed by filler-filler interaction.
