ABSTRACT
The present paper aims at finding the damping effect on the non-linear vibrational modes of a doubly curved shallow shell placed on an elastic foundation by using the method of constant deflection contour lines. The results obtained are compared with the available results and the method yields very satisfactory results which are in excellent agreement with the reference values.
