A three-dimensional unilateral contact problem for articular cartilage layers is considered in the framework of the biphasic cartilage model. The articular cartilages bonded to subchondral bones are modeled as biphasic materials consisting of a solid phase and a fluid phase. It is assumed that the subchondral bones are rigid and shaped like elliptic paraboloids. The obtained analytical solution is valid for monotonically increasing loading conditions.
在双相软骨模型的框架下，研究了关节软骨层的三维单侧接触问题。与软骨下骨结合的关节软骨被建模为由固相和液相组成的双相材料。假设软骨下骨是刚性的，形状为椭圆抛物面。得到的解析解适用于单调递增的加载条件。
