Band structure computation of in-plane elastic waves in 2D phononic crystals by a meshfree local RBF collocation method
In this paper, the band structures of in-plane elastic waves in two-dimensional (2D)
phononic crystals are calculated by using a meshfree local radial basis functions (RBF)
collocation method. In order to improve the stability of the local RBF collocation method,
special techniques suggested in our previous work for anti-plane waves are further
improved and extended for calculating the primary field quantities and their normal
derivatives required by the treatment of the boundary conditions in the local RBF collocation …
