Abstract: The governing equations of the free vibrations of spherical and cylindrical shells with a regular singularity are solved by Frobenius Series Method in the form of matrix.Considering the relationship of the roots of the indicial equation,we get somevarious expressions of solutions according to different cases.This work lays a foundation of solving certain elastic problems by analytical method.-
