Etude de l'influence de la vitesse de déformation sur la dimension fractale et sur la ténacité d'un polycarbonate

Abstract : The fractal index of the fracture surface of a polycarbonate in the mirror zone or fracture initiation zone has been determined by the spectral method. In the same time the fracture toughness of this polymer, the essential work of fracture has been measured. It can be seen that the fractal index decreases with the increasing of the fracture toughness. The study of he mutual influence of loading rate on these two parameters shows a transition connected with a change in the rheological behaviour
