    Purpose: Thermal stress and strain analyses of a thickness-stretched shear deformable microplate is studied in this paper based on principle of virtual work through a micro scale dependent theory. Methods: The general constitutive relations are developed in three dimensional based on generalized Hooke’s law. Thermal strain is included in the governing equations based on various temperature rising along the thickness direction. Results: An extended parametric analysis is performed in this paper after solution of the governing equations based on Navier’s technique. Numerical results are plotted in terms of temperature rising, micro-scale parameter along the thickness direction. Conclusions: The important difference of this paper with available materials in the literature is concurrent effect of thickness stretching ability and micro scale parameter.

    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.
