文摘A new term involving the rate of pressure change is introduced into the continuity equation of an existing biphasic mixture model. Based on this new continuity equation, a penalized numerical formulation of finite element method is given. Computational result shows that this new biphasic mixture model can provide better description of the transient response of biological media such as articular cartilage, muscle, and soft tissue.
