Simulation of Adaptive Bone Remodeling with Abaqus/Standard

In the adaptive bone remodeling process, the density of bone tissue changes over time according to the load it sustains. Elevated loads produce increases in bone den-sity while reduced loads cause reduction of bone density. The long term success of an orthopedic implant can be better predicted by including this process in the design workflow. In this Technology Brief, we demonstrate the Abaqus/Standard implementation of one of the leading bone re-modeling algorithms. User subroutine USDFLD is em-ployed to capture solution dependent material properties, and the approach is used in the analysis of a total hip re-placement design.
