Abstract

Double edge notched tensile (DENT) tests were carried out to investigate the slow crack growth (SCG) behavior of PE80 welded joints. Efforts were made to acquire creep fracture parameters which can characterize creep resistance. Results show that creep compliance indicates an ascending trend with the increase of applied stress. A global creep load parameter is obtained. It has a linear relationship with fracture time in logarithmic coordinate system and helps to predict the fracture time at any applied load.
