文摘

A thermographic analysis of heat sources accompanying the deformation of PMMA and PC polymers revealed several possible ways of introducing the thermoelastic coupling effects in the modelling. Therefore we used two basic linear viscoelastic models in which an elastic component was replaced by a thermoelastic branch. This Note highlights the practical interest of our approach for describing variations in thermoelastic sources during pulsating tensile testing of PMMA and PC samples. <strong>To cite this article: S.
