Abstract |
|
A novel meshless global radial basis reproducing kernel particle method (GRB-RKPM) is established based on the global radial basis function (GRBF) and the reproducing kernel particle method (RKPM). Subsequently, GRB-RKPM is used to solve the elastic mechanical of bidirectional functionally graded materials (BDFGMs). The influence of the shape parameter , the shape parameter , the scale parameter , and the penalty factor on the GRB-RKPM solving the elastic mechanical of BDFGMs is analyzed, and the optimal value is given. The effectiveness of the GRB-RKPM in solving the elastic mechanical of BDFGMs is verified by comparing solutions calculated by the GRB-RKPM with reference solutions calculated by the finite element method (FEM). Compared with the RKPM, the GRB-RKPM converges faster. The GRB-RKPM solutions are compared with the local radial basis reproducing kernel particle method (LRB-RKPM) solutions and the RKPM solutions. It is proved that the GRB-RKPM has higher computational accuracy. The deformation behavior of the elastic mechanical of BDFGMs under different gradient indexes is studied. |
