title: Relationship between fracture toughness and impact strength of acrylic bone cement.
abstract: This work involved determining the fracture toughness, KIc (in MPa(square root)m) (using rectangular compact tension specimens) and impact strength, IS (in kJ/m2) (Charpy type specimens) of Surgical Simplex P and three variants of Palacos R acrylic bone cements. The best fit to these results yielded a power relationship KIc = 0.795(IS)0.59. The usefulness of this relationship is detailed, especially for the purpose of performing quality control checks on bone cements.
