The relations of internal forces and strains, and of the moments and curvatures for an orthogonal-anisotropic plate whose principal axes of elasticity are slanted to its edges, were derived as in the equations (4), (5), (8) and (9). This plate has some interesting properties such that the simple stress or moment in only one direction will always cause the other two deformations than the direct one, as being shown in the above equations and Fig. 5, and that there are two cases in shear load, i.e., "normal shear" and "inverse shear", and these will accompany the contractions in x, y directions or the expansions. The effects of such contractions or expansions in shear on shear buckling loads were discussed. The most part of this paper was already reported at the meeting of "Committee on Research of Wooden Laminates for Airplanes" held 1944, sponsored by the former Air-Technical Laboratory of Navy.
