Bone is continuously remodeled through a coupled process of bone resorption and bone formation, and this process is called Bone Remodeling. Optimal remodeling is responsible for bone health and strength throughout life. Old bone is removed and new bone is created. Bone mass increases until a certain age, reaches its maximum, and then continuously declines for the rest of our lives. An imbalance in bone remodeling may cause diseases, such as osteoporosis or osteopetrosis. Loss of tissue matrix renders bones weak and susceptible to fracture. There are several theories about the mechanisms of bone remodeling, but none of these can predict all features of this process. We have derived a new model of bone remodeling using a continuum mechanics approach for a single phase continuous material and infinitesimal strains. In this model, volume fraction was replaced by the bone surface density in the constitutive laws governing the remodeling process. Also, we used an effective volume fraction that considers microcracks in an explicit manner.
