Extraction of polymer stress–strain behavior in the presence of self‐heating by the use of a simple model for the elastic–plastic deformation

摘要: Polymer materials are well known to be sensitive strain rate and temperature. Self-heating friction effects also play an important role in the mechanical response of these materials. Numerous constitutive laws phenomenological models have been developed take into account dependencies. This article proposes a simplified model based on mapping technique for temperature dependence. The adiabatic heating analyzed this work. Relatively good results obtained compared experimental polypropylene polychlorotrifluoroethylene. A parametric investigation interfacial equivalent stress (between specimen compressive bars) fraction plastic work converted heat was performed. study allowed approximation two parameters studied polymers.
