Effect of the weld-joint on fracture behaviour of polymer material
Original language description
Polyethylene pipeline for gas energy distribution should be carefully constructed to prevent an explosive gas from leaking, and the rate of failure should be very low. Therefore, there is a pressing need for reliable test procedures to evaluate the mechanical properties of welded joints. These tests are carried out either on coupons cut from the welded joint or on the complete weld, and can be either short-term or long-term. However, since the weld is more likely to fail in the long-term in service, itis important that the results from short term tests should be correlated with those from long term tests. Up to now, little work has been done to correlate results from short-term tests with those from long-term tests in the case of welded polymer pipes.To do this we need to understand the kinetics of crack initiation and its growth particularly through the welded joint. The first step is to study fracture behaviour of a polymer structure with a crack growing in or through the weld and
