Abstract
The accuracy of the Richardson extrapolation method is investigated for the eigenvalue problem of linear elasticity theory with zero Dirichlet boundary conditions in a three-dimensional beam. O(h 4)-estimates of eigenvalue and eigenfunction vector errors are obtained with the constraint that the eigenfunction belongs to the space W 42 (Ω).
