The strength of acrylic bone cements and acrylic cement-stainless steel interfaces. Pt. 1. The strength of acrylic bone cement containing second phase dispersions
The strength and fracture toughness of a surgical acrylic bone cement have been evaluated in air, saline solution, and a blood serum, and little effect of environment was observed. Second phase dispersions of either barium sulphate or glass spheres were found to have significant effects upon the strength and fracture surface energy. In the first composite, a decrease in strength and fracture surface energy may be explained in terms of the formation of voids around the barium sulphate particles and tearing of material between them. In the second composite, an increase in strength and fracture surface energy occurred through a crack front-glass sphere interaction effect. The occurrence of subcritical crack growth in the acrylic bone cement composites was investigated, and crack velocity-stress intensity factor diagrams were constructed for the purposes of fracture-safe design.
