Microstructural damage of cancellous bone under uniaxial compression

Microstructural damage of cancellous bone occurs as a result of daily functional loading conditions. However, bone has the ability to continuously repair the damaged regions with newly formed bone. The process is called bone remodeling and it plays an important role in the healing process of bone ti...
