采用数值方法求解了相似体和不相似体之间接触的经典Mindlin-Cattaneo部分滑移问题。结果表明，对于类似的机构，表面摩擦能量耗散集中的对称平面，虽然整体耗散是类似的经典解决方案所预测的。这种效应在不同材料的某些组合中得到增强，其中摩擦安定过程导致位移接触，从而导致额外的剪切柔量。
A numerical method is used to resolve the classic Mindlin-Cattaneo partial slip problem for contact between similar and between dissimilar bodies. It is shown that, for similar bodies, the surface frictional energy dissipation is concentrated off the plane of symmetry although the overall dissipation is similar to that predicted by the classical solution. This effect is enhanced for certain combinations of dissimilar materials, where the process of frictional shakedown leads to a displaced contact and hence additional shear compliances.
