  • Tg calculated is the glass transition temperature constrained by the heating rate, and Tmax relates to the maximum temperature emitted along the slip zone of a sample. For samples that rapidly failed, the temperature did not reach the glass transition interval, which prevented viscoelasticity analysis.
