Evaluation of Fracture Parameters by Coupling the Edge-Based Smoothed Finite Element Method and the Scaled Boundary Finite Element Method

This paper presents a technique to evaluate the fracture parameters by combining the edge based smoothed finite element method (ESFEM) and the scaled boundary finite element method (SBFEM). A semi-analytical solution is sought in the region close to the vicinity of the crack tip using the SBFEM, whilst, the ESFEM is used for the rest of the domain. As both methods satisfy the partition of unity...

Solidification Problems by the Boundary Element Method

This paper elaborates on the analysis and design of the solidification of pure metais. In the first part of this paper, a direct analysis is presented for the motion of the solid-Iiquid freezing interface and the time-dependent temperature field. An iterative implicit algorithm has been developed for this purpose using the boundary element method (BEM) with time dependent Green’s functions and ...

A Regular Indirect Boundary Element Method for Thermal Analysis

Hybrid Boundary Element Method in Acoustics

The aim of the present paper is, to employ the Hybrid Stress Boundary Element Method for the computation of acoustic scattering and radiation in innnite domains. The introduced method is based on multi-eld variational principles and leads to symmetric matrices. Starting from Hellinger-Reissner's principle in the frequency domain a two-eld hybrid principle for acoustics is developed allowing for...

BOUNDARY ELEMENT METHOD APPLIED TO THE LIFTING BODIES NEAR THE FREE SURFACE

In this study, the boundary element method is formulated to evaluate hydrodynamic characteristics of bodies including free surface effect. The method is based on two equations, the perturbation potential boundary integral and the pressure Kutta condition, which are solved simultaneously. The method uses isoparametric elements for both quantity and geometric on the boundary. The method is first ...
