Meshless analysis of high-speed impact
Theoretical and Applied Fracture Mechanics, 2005The governing equations for rate-independent large strain plasticity are formulated in the framework of meshless method. The numerical procedures, including return mapping algorithm, to obtain the solutions of boundary value problems in computational plasticity are outlined. The large strain plastic response of materials under high-speed impact/contact

Meshless Analysis of Ductile Failure
Volume 3: Design and Analysis, 2011We study ductile fracture using Reproducing Kernel Particle Interpolation and the Gurson-Tvergaard-Needleman (GTN) model. The meshless simulations are compared with the available experimental results and previous finite element simulations for crack propagation.

Stochastic Meshless Analysis of Elastic-Plastic Cracked Structures
New and Emerging Computational Methods: Applications to Fracture, Damage, and Reliability, 2002This paper presents a stochastic mesh-free method for probabilistic fracture-mechanics analysis of nonlinear cracked structures. The method involves enriched element-free Galerkin formulation for calculating the J-integral; statistical models of uncertainties in load, material properties, and crack geometry; and the first-order reliability method (FORM)

A Stable Meshless Method for Electromagnetic Analysis
2019 IEEE MTT-S International Microwave Symposium (IMS), 2019The major problem in applying a meshless (RPIM) method is that when a large number of sampling nodes is used, the condition number of the moment matrix increases, and numerical solution becomes unstable due to the required inversion of the matrix. To address the problem, in this paper, with the radial point interpolation meshless (RPIM) method as an ...

A Meshless Grain Element for Micromechanical Analysis
46th AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics and Materials Conference, 2005This study concerns the development of a 2-D meshless grain element for elastic deformation and intergranular damage initiation and propagation in polycrystalline fcc metals under static loading. A nonlinear constitutive model known as the cohesive zone model is employed to represent the inelastic interaction between the grain boundaries; thus ...

A meshless method and stability analysis for the nonlinear Schrödinger equation
Waves in Random and Complex Media, 2017In this paper, the non-linear Schrodinger (NLS) equation was solved by a meshless method based on the moving least-squares approximation. Single-soliton solution and interaction of two colliding solitons were studied to validate the accuracy of the proposed method.

PARAMETRIC STUDY FOR AN EFFICIENT MESHLESS METHOD IN VIBRATION ANALYSIS
Journal of Sound and Vibration, 2002Based on the moving least-squares (MLS) approach, an efficient meshless method is employed to generate the displacement functions for vibration analysis of elastic bodies. The equation of motion is established by following the standard procedure and the boundary conditions are imposed by applying penalty functions.

A MESHLESS ANALYSIS OF SHELLS BASED ON MOVING KRIGING INTERPOLATION
International Journal of Computational Methods, 2007An Element Free Galerkin Method (EFGM) for the analysis of degenerated shell structures is presented. The method is based on the Moving Kriging (MK) Interpolation function. The properties of the interpolation function possess the Kronecker delta property.
