Outline of Final Research Achievements |
In order to evaluate the bio-lubrication, this study investigated effective analysis methods for a moving boundary problem, an interaction between a fluid and elastic body, and deformation of a fluid-saturated porous media for the development of the coupled analysis of the fluid and porous elastic body which treats the flows inside and outside the articular cartilage and deformation of the articular cartilage. Although the coupled analysis of the fluid and porous elastic body has not been performed, the practical codes have been developed in terms of the numerical accuracy, stability and computational load.
