Experiments and numerical modelling of creep fracture behaviour of polyethylene PE100
The growing application of polymeric materials as structural materials,polyethylene in particular,demands new methodologies for assessing the material capability to withstand loads.The use of high density polyethylene pipes for water and gas distribution is one of the most common examples.The accurate modelling of fracture and viscous material responses of such structures represents a key to the prediction of structural integrity.In this paper the creep fracture mechanisms by slow crack growth in high density polyethylene PE100 are investigated,both experimentally and numerically.
