Abstract
The extended boundary-node method (X-BNM) has been modified for improving the accuracy degradation due to the boundary shape and its performance has been numerically investigated by comparing with the standard one. For the case where the boundary shape is strongly concave, the results of computations show that the accuracy of the modified X-BNM is always higher than that of the standard one. In addition, the speed of the modified X-BNM is almost equal to that of the standard one. Therefore, it is found that the performance of the modified X-BNM is much superior to that of the standard one.
