Hydrated soft tissues such as articular cartilage and intervertebral disc consist of a fluid phase composed of water and movable electrolytes and a solid phase composed of primarily collagen fibrils and negative changed proteoglycans. Understanding the etiology of degenerative disease of the hydrated soft tissues needs to elucidate the coupling mechanisms between mechanical, chemical and electrical phenomena. In this research, a finite element formulation for the hydrated soft tissues with large deformation was carried out based on triphasic theory. Numerical results are presented to demonstrate the mechanical behavior of triphasic structures. The effect of ion concentration on the mechanical behavior is also exemplified.
