Method used for construction of asymptotic solution of problem concerning natural oscillations of thin elastic shells taking into account initial momentless state of strain is presented. Known equations for states with large indices of variability are given. Boundary of application of method for shells of positive, zero and negative Gaussian curvature is established. As example, oscillation of spherical panel, supported on right angle in generalized meaning by contour and loaded gas pressure is considered.
