Mixing techniques used to reduce porosity in bone cement demonstrate large improvements in fatigue behaviour in test specimens, but do not appear to reduce the rate of loosening of implants in vivo. We examined data showing the effect of notches on fatigue strength and found, surprisingly, that notches with low stress-concentration factors (Kt Keywords: mixing technique, fatigue strength, bone ...
When a cement-treated base layer is subjected to repeated stress, inherent microcracks begin to propagate and coalesce from the bottom of the layer and finally cause the layer to fail. In order to identify the rate of fatigue failure of the cement-stabilized base layer, Paris´ law, da/dN = A(?Kmax)n, can be used.In this research, the parameters, A and n, were predicted by a viscoelastic approach. ...
