Correlation between impact strength and fracture toughness of PMMA-based bone cements
Abstract
The thrust of the work involved determining the impact strength, IS (in kJm-2) [using non-ASTM-sized Charpy-type specimens and an in-house impact tester] and fracture toughness, K(Ic) (in MPa√m) [using ASTM-sized rectangular compact tension specimens] of Surgical Simplex(®) P and three variants of Palacos(®) R acrylic bone cements. The attractions and drawbacks of this method for determining IS are detailed. The best fit to the K(Ic) and IS results yielded a power relationshipK(Ic)=0.795(IS)0.59.The usefulness and limitations of this relationship are detailed. Copyright (C) 2000 Elsevier Science Ltd.
