Background, Motivation and Objective The piezoelectric-piezomagnetic(PE-PM) sandwiched structures are consisted of layered piezoelectric and piezomagnetic materials. They are easy to be manufactured and possess superior magnetoelectric(ME) coupling effect. With these superiorities, the PE-PM sandwiched structures have been widely used in sensors, transducers and acoustic wave devices and so on. However, due to the fragility of the materials and complicated in-service loading conditions, the PE-PM sandwiched structures tend to fracture easily. So, it is essential to research the internal crack in PE-PM sandwiched structures under electro-magneto-mechanical coupled loadings. However, up until now, there is no paper studies the mode-I crack in PE-PM-PE sandwiched structure under in-plane electro-mechanical coupled loading. From the above, considering the magnetic field of piezoelectric material and the electric field of piezomagnetic material, a mode-I internal crack problem of a PM layer bonded to two PE layers is studied in this paper. Statement of Contribution/Methods This paper contributes to obtaining an analytical solution by using the integral transform technique. Firstly, the Fourier transforms are applied to the governing equations, and a set of appropriate solutions are obtained with some unknown functions. Then, substituting the appropriate solutions into boundary conditions meanwhile considering the magnetoelectric permeable crack plane conditions, we could derive the dual integral equations after the complex mathematical process. In order to obtain the magneto-electro-elastic field in the near of the crack tip, the dual integral equations are reduced into the singular integral equations with cauchy kernel of the second kind. Finally, the cauchy singular integral equations will be solved by Gauss-Jacobi collocation method. Meanwhile, the field intensity factors(FIFs) could be obtained. Results In this paper, an integral transform technique is employed to re
