WebApr 11, 2024 · Direction of shift Support for temperature-related expected range shifts. We removed longitudinal shifts for temperature-related analyses, leaving us with 29,881 range shift estimates. Less than half of all the raw observations supported common range-shift expectations (i.e., towards the poles, higher elevations, deeper depths; 46.63%). Webthe temperature up to 50°C and then increased or maintained a stable value when the temperature increased up to 60°C. The time-temperature superposition (TTS) principle was extended to construct the dynamic modulus master curve of the MREs by using the horizontal shift factor and the vertical shift factor.
WebSep 29, 2024 · The amount that each individual curve needed to shift to create the master curve is the time–temperature shift factor. Shift factors for PA are plotted as an Arrhenius-type plot in Fig. 6. This curve is a straight line at temperatures above 40 °C, indicating that creep phenomena comply with the TTSP in Arrhenius mode. WebTIME - TEMPERATURE SUPERPOSITION PRINCIPLE ...
