Abstract: “Radial basis functions (RBFs) are the functions whose values depend only on the distance from the point called center. These functions are employing in the approximation theory and they can be utilized in the point interpolation method as a type of meshless approach for constructing the shape function. This paper discusses on the results of RBF-based meshless numerical modeling of wave propagation for additional mass detection in isotropic rod which it can be assumed as damage. Number of nodes, position and magnitude of additional mass and the variation of multiauadric RBF parameters have been studied in this paper.”
