The possibility of predicting the resistance to creep and ductile failure in pressurized pipes from tensile creep tests on specimens taken from the same pipes, is explored. Experimental results obtained by the two testing methods are compared and discussed.

Creep fracture tests were canied out on a pipe grade polyethylene using arc-shaped notched specimens loaded in four point bending. Under all conditions examined, discontinuous crack growth was observed. The fracture process is analysed considering each single stage of the discontinuous crack propagation independently....
