THE EFFECT OF THE STRAIN RATE ON THE J-R CURVE OF POLYETHYLENE

摘要

The usefulness of the J-integral concept for the characterisation of the fracture behaviour of polyethylene is determined by studying the effect of the strain rate on the J-R curve of three different brands of polyethylene. The CTOD during the experiments is also measured to determine the applicability of EPFM fracture mechanics by comparing the J and the CTOD.
