Following previous results showing that under the static loads it is alsopossible to detect the first plasticization of the specimens at the end of the thermoelasticphase, the authors conducted experimental trials to verify that this effect can be put inevidence in notched and unnotched PVC specimens. The goal was to define the realelastic phase also for material in which the elastic limit and the yield are not easilydefined, differently from than that for steel. The results showed a variable thermalbehaviour in the value of the thermoelastic limit and in the interval between this oneand the yield in function of the distance from the notch. The limits so enhanced allowfor following the paths of plasticization.
