An approximate method is suggested for solving the two-dimensional problem of the theory of elasticity of an infinite, anisotropic plate with an almost circular opening. The method is based on the introduction of a small parameter characterizing the deviation of the opening from the circular. The problem is reduced to the problem of the equilibrium of an anisotropic plate with a circular opening. Chief attention is given to an opening having four axes of symmetry. Approximate solutions for a plate with such an opening are derived for both the general case of loading and for two particular cases when the plate is orthotropic and is deformed by 1 tensile stresses and 2 bending moments.
