Numerical procedures in obtaining upper and lower bounds to eigenvalues of various beam problems are presented. Various numerical problems and their cure when applying the bounding procedures are discussed. Upper bounds are obtained using the well-known Rayleigh-Ritz procedure and lower bounds are obtained using methods developed by Bazley and Fox AD-608 356 Lower bounds to eigenvalues using operator decompositions of the form BB. Archive for Rational Mechanics and Analysis, 10352-60 1962. Computational examples are given and tables of upper and lower bounds are displayed. Author
