| Abstract: |
| In this paper, the meshless radial point interpolation method(RPIM) is applied to carry out the topology optimization of the continuum structure. Considering the relative density of nodes as design variables, and the minimization of compliance as an objective function, the mathematical formulation of the topology optimization is developed using the SIMP(solid isotropic micro-structures with penalization) interpolation scheme. The optimization formulation is solved by the optimality criteria method. Numerical examples show that the proposed approach is feasible and efficient for the topology optimization of the continuum structure, and can effectively overcome the checkerboard phenomenon. |
