AN ELASTIC CIRCULAR CYLINDER WITH DISPLACEMENT PRESCRIBED AT THE ENDSAXIALLY SYMMETRIC CASE
( Department of Engineering Science and Applied Mathematics, Northwestern University Evanston, Illinois 60201, USA )
The problem of a linear elastic cylinder with a stress-free curved surface and prescribed displacements at the plane ends is solved by the development in terms of eigenvalue expansions. Then, a biorthogonality relationship for the axially symmetric case is obtained, which is seen to have convergence difficulties. These are surmounted through use of a Galerkin approach, which yields a more diagonally dominant system. To obtain results at the plane ends special techniques have to be developed that correctly incorporate the singular behaviour there.
