The concepts of linear elastic fracture mechanics (LEFM) are applied to three grades of high density polyethylene in an attempt to determine their fracture behavior in terms of a linear elastic fracture toughness, K c . The effect of specimen size (thickness and width), crack length and the mode of loading on K c has been investigated in order to determine the plane strain fracture toughness, K Ic , of these materials. The effect of temperature (between +23 and −180°C) on their fracture behavior has also been investigated and compared in terms of their plane strain fracture toughness values.
