ANALYSIS OF 2-D THIN STRUCTURES BY THE MESHLESS REGULAR HYBRID BOUNDARY NODE METHOD

<正> Thin structures are generally solved by the Finite Element Method(FEM),using plate orshell finite elements which have many limitations in applications,such as numerical locking,edge effects,length scaling and the cnvergence problem.Recently,by proposing a new approach to treating the nearly-siagnlar integrals,Liu et al.developed a BEM to successfully solve thin structures with the thickness-to-length ratios in the micro-or nano-scales.On the other hand,the meshless Regular Hybrid Boundary NodeMethod(RHBNM),which is proposed by the current authors and based on a modified functional and theMoving Least-Square(MIS)approximation,has very promising applications for engineering problems owingto its meshless nature and dimension-reduction advantage,and not involving any singular or nearly-singularintegrals.Test examples show that the RHBNM can also be applied readily to thin structures with high accu-racy without any modification.
