An implicit numerical algorithm for the integration of the primary/secondary creep constitutive law at the material point level is derived.
Introduction The growing application of polymeric materials as structural materials, polyethylene in particular, demands new methodologies for assessing the material capability to withstand loads.
The accurate modelling of fracture and viscoelastic material responses of such structures represents a key to the prediction of structural integrity.
