Abstract

• The primary aim of this work was to re-examine the range of applicability of linear elastic fracture mechanics (LEFM) to environmental stress cracking of low-density polyethylene. By use of a number of specimen types and a range of specimen dimensions and loads it is shown that the K I-c relationship is unique only at low K Is. The material studied showed a region of constant crack velocity which was not caused by plasticity effects or the failure of LEFM. However, crack arrest, which occurred at high K Is or loads, was shown to be caused by ductile yielding causing the crack to blunt. �� 1986 Chapman and Hall Ltd.
