摘要	A novel extended traction boundary element-free method is proposed to analyze the crack problems of two-dimensional infinite magnetoelectroelastic solid. An extended traction boundary integral equation only involving Cauchy singularity is firstly derived. Then, the extended dislocation densities on the crack surface are expressed as the combination of a characteristic term and unknown weight functions, and the radial point interpolation method is adopted to approximate the unknown weight functions. The numerical scheme of the extended traction boundary element-free method is further established, and an effective numerical procedure is used to evaluate the Cauchy singular integrals. Finally, the stress intensity factor, electric displacement intensity factor and magnetic induction intensity factor are computed for some selected crack problems that contain straight, curved and branched cracks, and good numerical results are obtained. At the same time, the fracture properties of these crack problems are discussed.
