Abstract (EN):
This work presents the large deformation analysis of non-linear elastic and elasto-plastic structures based on an improved meshless method, the Natural Neighbour Radial Point Interpolation Method (NNRPIM). The NNPRIM uses the Natural Neighbour concept in order to enforce the nodal connectivity and the Delaunay triangles to create a node-depending background mesh used in the numerical integration of the NNRPIM interpolation functions. The NNRPIM interpolation functions are constructed using the Radial Point Interpolators, with some differences that modify the method performance. Several non-linear elasto-plasticity problems are studied to demonstrate the effectiveness of the method. © Civil-Comp Press, 2009.
