The most popular boundary method is the boundary element method (BEM ) or boundary integral equa­ tion method as it is sometimes called. Also one particular case of the boundary methods is the boundary collocation method iBCM) which is not very popular in comparison with the BEM. An extensive review of the BCM is given in Kolodziej (1987). There exist a number of papers which attempt to compare the 53 54 accuracy of results obtained by the BCM with the exact solu­ tions obtained analytically, for instance Barta (1937), Conway (l960),Hooke (1969), Leissa, Lo, Niedenfuhr (1965), Redekop (1982), Wah (1979)-On the other hand, the performance comparisons of BCM and other approximate methods are not nume­ rous.
