Abstract : The author solves the plane problem from the theory of elasticity for the stressed state of a rectangular orthotropic plate using a simple method for determining the constants of integration applicable to an isotropic plate. The constants of integration are found directly as coefficients of the Fourier expansion for the edge load, assuming that the plate is subjected to arbitrary normal and tangential forces with respect to the long sides. Experimental and theoretical stresses are compared for a plate made from fiberglass-reinforced plastic and for a corrugated plate with shallow corrugations. The results show satisfactory agreement which indicates that the proposed method is applicable to problems of this type and should result in a considerable reduction of time and labor in solving complex contact problems.
