Abstract (EN): In this work, the radial point interpolation technique (RPI) is extended to the analysis of material showing an elasto-plastic behavior. The RPI methodology discretizes the problem domain using only a set of scattered nodes, randomly distributed along the problem domain. Here, the RPI formulation is fully described as nodal connectivity; influence-domains; and shape functions. Additionally, the system of equations, obtained from the weak formulation of Galerkin is presented. Afterwards, the elasto-plastic numerical formulation, which is here adapted to the RPI formulation, is presented and the Newton-Raphson non-linear solution method is described with detail. Several benchmark examples are solved, using both the proposed methodology and the finite element method. In the end, the results are compared and discussed. © 2017 Nova Science Publishers, Inc.
