This paper presents the application of the topological optimization in plane elasticity problems applying the boundary element method (BEM) coupled with the evolutionary structural optimization (ESO) procedure by using initial stress fields as the ne

SUMMARY It is well known that solutions for linear partial differential equations may be given in terms of fundamental solutions. The fundamental solutions solve the homogeneous equation exactly and are obtained from the solution of the inhomogeneous

In this paper a procedure based on the hypersingular element method is applied to find the TE and TM modes in arbitrarily shaped waveguides. To show the accuracy of this method, various examples are solved and the results are compared to those analyt

In meshless methods based on weak formulation, the governing integral equation is obtained from the weak form of elasticity over global or local domains. Many of the so-called meshless methods, such as the element-free Galerkin (EFG) method [Belytsch

This work considers the detection of the spatial source term distribution in a multidimensional linear diffusion problem with constant (and known) thermal conductivity. This work can be physically associated with the detection of non-homogeneities in

In this paper we consider the application of the method of fundamental solutions to solve crack problems. These problems present difficulties, which are not only related to the intrinsic singular nature of the problem, instead they are mainly related

The work presented here concerns the use of radial basis functions (RBFs) for the analysis of two dimensional elastostatic problems. The basic characteristic of the formulation is the definition of a global approximation for the variables of interest

In this work the element-free Galerkin (EFG) method is used for damage analysis of reinforced concrete beams. The chosen damage model is that due to Mazars whereby the concrete is represented by an elastic medium with progressive damage. As usual in
