Abstract
This work analyzes the fracture toughness under LEFM and EPFM conditions of high density polyethylene specimens sharpened via contact procedures such as razor pressing and broaching and non-contact procedures such as femtolaser and fatigue. The fatigue notch sharpening was accomplished following the guidelines for fatigue pre-cracking in metals. Under LEFM conditions, there was no influence of the notch sharpening technique on the fracture toughness but under EPFM conditions, the fracture toughn...
