Abstract:
We have researched the viscoelastic properties of the cancellous bones of the os calcaneus, os lunatum and os capitalum. The compressing stress relaxation experiment and the creep experiment in the vertical, horizontal and 45 degree directions on the os calcaneus were performed. The data and curve of the compressing stress relaxation and creep were obtained. By masing regression analysis we worked out the compressing reduced stress relaxation and creep functions and curves. The results show that the quantities of compressing stress relaxation and creep of the calcaneus in the vertical direction are larger than those in the other two directions. The initial quantities of creep of the os capitalum are larger than those of the os lunatum, and there are no significant different between the quantities of stress relaxation of the cancellous bones of the os lunatum and os capitalum.
