The bone remodeling process is investigated theoretically and experime ntally within the framework of extended adaptive elasticity. Coupling between in ternal and surface remodeling is considered to better simulate the bone remodeli ng process. The interactions of multifield loading, including transverse press u re, electrical fields, and magnetic fields, are taken into account when simulati ng bone remodeling. A semianalytical solution based on the statespace method w as used to analyze the remodeling process of inhomogeneous bone materials subjec ted to multifield loading. Numerical examples are presented to verify the prop o sed theoretical model for coupled internal and surface bone remodeling under mec hanical and electromagnetic loading. The results are in contrast to former work which did not consider coupling between internal and surface remodeling. The mag nitude of electrical field changes is found to be lower and the remodeling time is significantly shorter. This implies that the coupling between internal and su rface remodeling plays an important role in the bone remodeling process. On the other hand, the results show that environmental loading can change the structure and properties of bone tissues.
