建立了各向异性压电/压磁复合材料在平面或圆形压模下的摩擦滑动接触模型。单斜各向异性压电/压磁复合材料的特征方程为十阶方程。所述的问题是减少到积分方程的内核提出了一个非常规的奇异性。参数研究表明，复合材料的体积分数和摩擦系数可以显着影响的摩擦学行为。数值结果表明，表面量在压模边缘处具有奇异性或尖峰，压电/压磁复合材料中的磁电耦合不存在于任何单一相中。
A frictional sliding contact model is established for the anisotropic piezoelectric/piezomagnetic composites indented by a flat or circular stamp. The characteristic equation related to monoclinic anisotropic piezoelectric/piezomagnetic composites is of tenth-order. The stated problem is reduced to integral equations whose kernels present an unconventional singularity. Parametric studies reveal that both the volume fraction of the composites and the friction coefficient could significantly affect the tribological behaviors. Numerical results show that the surface quantities have a singularity or spike at the stamp edge, and that the magneto-electro coupling in piezoelectric/piezomagnetic composites does not exist in any single phase.
