Abstract

The critical level of degradation for fracture initiation and the speed of stress corrosion crack (SCC) propagation depend on the rates of toughness deterioration and buildup of die degradation related stresses as well as on the manufacturing and service stresses. Some PE samples tested using an aggressive environment at various test conditions, are investigated. SEM and FTIR analysis of PE pipes fractured in accelerated test are applied to validate the proposed model of crack initiation and propagation in PE. SEM is useful to identify the change of fracture mechanisms from chemical degradation driven crack to mechanically driven crack by the formation of visible striations. FTIR analysis enables to quantify by means of carbonyl index the chemical degradation on the crack surface.
