ABSTRACT
Today, the use of high-density polyethylene (HDPE) pipes dominates underground fluid transport sector especially when replacing traditional and costly steel, cast iron and copper pipes. The failure of polyethylene pipes can occur due to a variety of factors such as excessive external loads, environmental stress cracking phenomenon, thermal gradients, manufacturing methods of and effective service conditions. It is essential to have as complete understanding as possible of the HDPE fracture behavior from modeling methods. This work is focused to quantify fracture energies of highly resistant polyethylene (PE) pipe by finite element method using the J-integral fracture criterion for different length of notch. The initiation of a crack is described by a critical value, JIC (kJ/m2) and a critical displacement (uc).
