Abstract

Bone cement creep behavior was studied using commercial available clinical bone cement. Creep deformation was measured using a micrometer with a resolution of 1 μm. It was demonstrated that the restraint has a very strong effect on the creep of bone cement, half-restrained specimens creep more than that of fully restrained specimens. The creep of the investigated bone cement increased with the dynamic loading cycles, and two creep stages, a high initial creep rate followed by a steady creep stage, can be identified. The relationship between the creep deformation and the loading cycles was expressed by a single logarithmic model.
