In this paper, first two modifications made on the adaptive elasticity theory (AET) will be introduced. In the first modification, the commonly used “volume fraction” will be replaced by a new parameter, so-called “free surface density”, based on the fact that all bone resorption and formation occurs on bone free surfaces. The novelty of our approach is that one can observe the effect of bone geometry and mass distribution on the rate of remodeling. Moreover, a single equation can be found for both surface and internal remodelling. Then, in the 2nd modification, we have introduced microdamage factor and defined effective volume fraction of bone, based on the fact that microdamage can initiate bone remodeling process. Using our new model, the simultaneous effect of mechanical stimuli, their rates, and also their history can be seen in the rate of bone remodelling. Finally, a modification was made on a semi-mechanistic bone remodeling theory by considering the cellular accommodation effect and simultaneous effects of microdamage and disuse. Using our last model, it was shown that the temporal sequence of loading can affect the rate of bone remodeling, which is in agreement with recent experimental evidence.
