USING THE NET-POINT METHOD IN STRESS ANALYSIS OF ORTHOTROPIC WINGS WITH SMALL ASPECT RATIO,

Abstract

An examination was made of bending of a low aspect orthotropic wing for different cases of retention: retention over the entire side chord, retention on a part of a chord, and retention on part of a chord with point supports. The load is presumed to be arbitrarily distributed. The problem is solved within the theory of bending of orthotropic plates of variable thickness by the method of finite differences. Such a solution permits taking into account the variability of sections and different moduli of elasticity at any point. The method of finite differences permits taking into account various important boundary conditions and makes it possible to utilize computer techniques, since the simplicity of the mathematical apparatus and the similarity of the calculations simplify programming for computers.
