Modelling Elasto-Plasticity Using the Hybrid MLPG Method [PDF]
Computer Modeling in Engineering & Sciences, 2010 Meshless methods continue to generate strong interest as alternatives to conventional finite element methods. One major area of application as yet relatively unexplored with meshless methods is elasto-plasticity. In this paper we extend a novel numerical method, based on the Meshless Local Petrov-Galerkin (MLPG) method, to the modelling of elasto ...

The Numerical Solution of Fractional Black‐Scholes‐Schrodinger Equation Using the RBFs Method
Advances in Mathematical Physics, Volume 2020, Issue 1, 2020., 2020 In this paper, radial basis functions (RBFs) method was used to solve a fractional Black‐Scholes‐Schrodinger equation in an option pricing of financial problems. The RBFs method is applied in discretizing a spatial derivative process. The approximation of time fractional derivative is interpreted in the Caputo’s sense by a simple quadrature formula ...

Further Developments in the MLPG Method for Beam Problems
Computer Modeling in Engineering & Sciences, 2003 An accurate and yet simple Meshless Local Petrov-Galerkin (MLPG) formulation for analyzing beam problems is presented. In the formulation, simple weight functions are chosen as test functions as in the conventional MLPG method. Linear test functions are also chosen, leading to a variation of the MLPG method that is computationally efficient compared to
