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.
