Impact speed dependency of the ductile failure threshold temperature for a plasticized polyvinylchloride

With the goal of ensuring security passengers for automotive industry, present work addresses temperature and impact speed envelope allowing ductile failure plasticized PVC to be obtained. A database about 250 test results has been constructed various conditions at ten temperatures, four speeds two specimen geometries (with or without scoring). The desired was characterized by shape load versus deflection curve together with fracture surface morphology temperatures obtaining threshold ( $$T_{\mathrm {dth}}$$ ) have plotted as a function geometries. gap 20 $$^{\circ }$$ C on highlighted between Additionally, strength under study estimated 0.25 kJ/m $$^2$$ .
