    Electro-magneto-thermo-mechanical critical loads of a sandwich microplate composed of a core integrated with piezoelectric/piezomagnetic face-sheets are analyzed in this paper based on higher order shear and normal deformation theory and modified couple stress theory. The constitutive relations are developed based on generalized Hooke’s law and electromagnetic relations. In order to measure athletic performance and his/her quantitatively or qualitatively grades, a force plate is used. The thickness stretching of the sport force plates is accounted based on a new function in displacement field. The electric and magnetic potentials are assumed as summation of a linear function including applied electric/magnetic potential and two functions for satisfying the zero condition at top and bottom of the sport force plates.
