STATISTICS OF EIGENSOLUTIONS FOR SYSTEMS WITH RANDOM SHAPE-PARAMETERSUSING BEM

This paper presents a probabilistic boundary element method for analys is of the statistics of structural eigenvalues and eigenvectors, when the shape parameters of the structures are considered as random variab les. Using this method, engineers are able to estimate the errors of t he structural eigenvalues and eigenvectors resulting from manufacturin g errors, and evaluate the differences between the experimental result s and numerical results, which are given by the finite element method or boundary element method, etc. This method can be used to design and analyse the components of engineering structures because of its simpl icity and effectiveness.
