The resistance to failure under an oscillating load, fatigue, and to failure under constant load (CL), are presented for a large number of linear polyethylenes. The effects of fatigue and a CL on brittle fracture are compared with respect to the influence of the molecular structure such as branching and the molecular weight. Molecular weight has a relatively greater influence on fatigue, whereas branching is more important under CL.
