The open profile thin elastic wavy shell natural oscillations problem is considered. The proposed method for determining the numerical values of the lowest frequencies and the corresponding forms of natural vibrations of shells with a complicated shape is based on the Rayleigh-Ritz energy method. The results of numerical calculation for a thin wavy shell with a rigidly pinched lower contour are presented.
