双相材料广泛应用于关节软骨的建模和数值模拟。结合接触，所产生的离散系统的数值解是一项艰巨的任务，特别是对于现实的几何形状。我们考虑了不同的多级方法的稳定性和效率的数值解所产生的非光滑系统。此外，多层次的方法推导出允许有效的数值模拟两相材料接触。给出了三维空间中具体几何问题的数值例子。（© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA，魏因海姆）
Biphasic materials are widely used for the modelling and the numerical simulation of articular cartilage within joints. In combination with contact, the numerical solution of the arising discrete systems is a demanding task, in particular for realistic geometries. We consider the stability and efficiency of different multilevel approaches for the numerical solution of the resulting non–smooth systems. Moreover, multilevel methods are derived which allow for the efficient numerical simulation of biphasic materials in contact. Numerical examples on problem specific geometries in three space dimensions are given. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
