THE UPPER BOUND PROPERTY FOR SOLID MECHANICS OF THE LINEARLY CONFORMING RADIAL POINT INTERPOLATION METHOD (LC-RPIM) [PDF]
International Journal of Computational Methods, 2007 It has been proven by the authors that both the upper and lower bounds in energy norm of the exact solution to elasticity problems can now be obtained by using the fully compatible finite element method (FEM) and linearly conforming point interpolation method (LC-PIM).

Modeling of Shear Crack Propagation in Rock Masses Using Mesh‐Free LRPIM
Advances in Civil Engineering, Volume 2021, Issue 1, 2021., 2021 The modeling of shear cracks in materials is critical in various engineering applications, such as the safety analysis of concrete structures and stability analysis of rock slopes. Based on the idea of Goodman element, the elastic‐plastic constitutive model of the shear cracks is derived, and the elastic‐plastic analysis of shear crack propagation is ...

An improved meshless method for finite deformation problem in compressible hyperelastic media
Vietnam Journal of Mechanics, 2021 Hyperelastic materials are considered as special category of elastic solid materials because of their nonlinear complicated constitutive laws. Due to large strain state, the behaviour of such materials is often considered in finite deformation analysis.

Two-dimensional beams in rectangular coordinates using the radial point interpolation method
REM: International Engineering Journal, 2019 The three-dimensional Theory of Elasticity equations lead to a complex solution for most problems in engineering. Therefore, the solutions are typically developed for reduced systems, usually symmetrical or two-dimensional. In this context, computational
