Unsteady Thermo-Elastoplastic Analysis by Triple-Reciprocity Boundary Element Method

Boundary Element Method with Automatic Progressive Cell Generation for Elastoplastic Analysis

An adaptive automatic cell generation for elasto-plastic problems has been developed which eliminates the need of user definition of the cells. These are progressively generated only on those points where plasticity occurs. Unnecessary domain computations are avoided, which leads to a gain in efficiency. The new method has been tested on examples and the accuracy of the results is in agreement ...

Petroleum reservoir engineering applications of the dual reciprocity boundary element method and the green element method

Petroleum reservoir engineering requires solutions to the transient diffusion and convection-diffusion equations. Traditionally these calculations are carried out using finite difference methods. Prior workers have used perturbation-based boundary element methods for single phase flow in heterogeneous media. The current work applies the Dual Reciprocity Boundary Element Method (DRBEM) and the G...

Scattered Data Interpolation based on Dual Reciprocity Boundary Element Method with Unknown Boundary Conditions

A numerical method based on Dual Reciprocity Boundary Element Method (DRBEM) has presented to interpolate twodimensional data with arbitrary pattern. This method is performed without specific boundary conditions. It claimed that interpolation function is true on the Poisson equation with unknown source function. The source function is estimated by radial basis functions expansion. Finally, nume...
