The singularities of the coupled fields near the apex of a piezoelectric/piezomagnetic composite wedge under antiplane deformation were studied.With the complex variable function theory and the eigenfunc-tion expansion method,the explicit expressions of the eigenfunction equations for singularity orders were de-rived for 16 combinations of mechanically free or clamped,electrically closed or open and magnetically closed or open ones.Based on the obtained eigenequations,some numerical results were given to show the influences of the wedge angles,boundary conditions and material combination types on the singular behaviors.The results show that,the singularities of the coupled fields in a piezoelectric/piezomagnetic composite wedge are more complicated than those in a piezoelectric counterpart.
