With the use of three-dimensional relations of the mechanics of deformed bodies, the spatial problem of stability of a rectangular double-base stratified orthotropic plate in a heterogeneous subcritical state as an element of the construction made of a composite at the different values of a geometrical parameter characterizing the sizes of the plate is investigated. The solution of the problem comes true in the exact statement with the use of the equations of linear elasticity theory and the three-dimensional linearized theory of stability. For the construc are solved by numerical methods.
