Summary This study investigates the use of the essential work of fracture (EWF) test in UHMWPE for use in orthopedic implants. A simplest method to produce the notch and initial crack was used. The validity of the fracture toughness results obtained by this method was investigated to evaluate the possibility of using this technique in obtaining data for the design of orthopedic prostheses.
