  This article addresses the experimental characterization of the temperature aging effect on tensile fracture load behavior of notched and unnotched high density polyethylene material. The samples were cut from a HDPE pipe. After mechanizing the tensile specimens with a numerical controlled machine, two series of samples were mechanized with different types of notches. The first series was drilled with a different central hole of diameter 4,6 and 8 mm. In the second series, one group of specimens the V shape notches were carried out on one side of samples, while for the second group the V shape notches were carried out on the double sided of specimens. Once the notches mechanized, the samples were exposed into a room temperature to positive and a negative temperatures -40?C and 100?C during 72 hours. The planning design experiment approach was applied to obtain a mathematical model tak.. Read More»
