Edge Effect in a Two-layer Orthotropic Strip

Abstract

The article discusses the edge effect (boundary layer, Saint-Venant effect) of a two-layer strip of orthotropic materials. Two methods are used to solve the problem of plane elasticity (solution in stresses and displacements). Both methods are constructed in such a way that they can describe the edge effect. This allows us to construct a theory for calculating the edge effects of single-layer strips based on which we manage to solve the problem of calculating the edge effect of two-layer strips analytically accurately. In fact, the problem can be summarized by saying that it is calculation of a single-layer strip. The obtained numerical results show that both methods of solution lead to the completely coinciding results.
