Abstract

The eXtended Boundary Node Method (X-BNM) with the periodic Radial Point Interpolation Method (RPIM) shape function is proposed and its performance is investigated numerically. The results of computations show that the accuracy of the X-BNM with the periodic RPIM shape function is almost equal to that with the Moving Least-Squares (MLS) shape function. In addition, the speed of the X-BNM with the periodic RPIM shape function is extremely faster than that with the MLS shape function. Therefore, the periodic RPIM shape function is useful for improving the performance of the X-BNM.
