In this paper the application of the mesh-free method (MFM) for the elasto-plastic analysis of reinforced soils is studied for the first time. The applied mesh-free method is called the radial point interpolation method (RPIM). In MFM, unlike the finite element method (FEM), there is no need of mesh in the traditional sense, and the shape functions are based on nodes. In the present study the r...

This paper presents a novel formulation for static limit analysis of structures, which the Airy stress function is approximated using stabilized Radial Point Interpolation Mesh-free method (RPIM). The field determined as second-order derivatives function, and equilibrium equations are automatically satisfied priori. so-called Stabilized Conforming Nodal Integration (SCNI) employed to ensure pre...

This work investigates fracture characteristics of a marble semi-circular bend (SCB) specimen with pre-defined crack under compressive loading condition. It aims at evaluating how the toughness can be affected by and span length variation. Numerically, model is solved using meshless methods, extended to linear elastic mechanics (LEFM), resorting radial point interpolation method (RPIM) its natu...

This paper presents a novel topology optimization approach without calculation of sensitivity for the minimum compliance problems, based on meshfree Radial Point Interpolation Method (RPIM). Relying algorithm Proportional Topology Optimization (PTO), material is distributed using only information objective function (which elastic strain energy). Material properties are interpolated by well-know...
