Mmds and 2d scattering problem by cylindrical structure with piece-wise smooth boundaryMmds and 2d scattering problem by cylindrical structure with piece-wise smooth boundary
(2009-02-20)
An universal modification of the method of discrete sources (MMDS) was appliedfor solving 2D Dirichlet or Neumann boundary problem when the scatterer’s contour isa piece-wise smooth contour. The problems of accuracy, ...
Vibration analysis of shear deformable shallow shells using the Boundary Element Method
(2014)
In this work, the modal and harmonic analysis of elastic shallow shells, using a Dual Reciprocity Boundary Element formulation, is presented. A boundary element formulation based on a direct time-domain formulation using ...
Boundary element analysis of shear deformable shallow shells under harmonic excitation
(Tech Science Press, 2014)
In this work, the harmonic analysis of shallow shells using the Boundary Element Method, is presented. The proposed boundary element formulation is based on a direct time-domain integration using the elastostatic fundamental ...
Transient dynamic analysis of shear deformable shallow shells using the boundary element method
(Elsevier Ltd, 2015)
The complexity involved in the dynamic response of plates brings many challenges from a mathematical standpoint. In this work, the transient dynamic analysis of elastic shallow shells under uniformly distributed pressure ...
Boundary element analysis of laminated composite shear deformable shallow shells
(Elsevier Ltd, 2018)
In this work, a Boundary Element Method formulation for stress analysis of symmetrically laminated composite thick shallow shells is presented. The proposed formulation was obtained by coupling the boundary element formulation ...
A Dirichlet-to-Neumann finite element method for axisymmetric elastostatics in a semi-infinite domain
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2017)
The Dirichlet-to-Neumann finite element method (DtN FEM) has proven to be a powerful numerical approach to solve boundary-value problems formulated in exterior domains. However, its application to elastic semi-infinite ...

Three-dimensional BEM analysis to assess delamination cracks between two transversely isotropic materials
(Mathematical Science Publ, 2011-12-21)
Beyond the inherent attribute of reducing the dimensionality of the problem, the attraction of the Boundary Element Method (BEM) to deal with fracture mechanic problems is its accuracy to solve strong geometrical ...
A boundary element formulation to perform elastic analysis of heterogeneous microstructures
(2018-02-01)
A BEM formulation to perform elastic analysis of heterogeneous microstructures is proposed in the context of multi-scale analysis. The microstructure, also denoted as RVE (Representative Volume Element), is modeled as a ...
Isogeometric boundary element methods for three dimensional static fracture and fatigue crack growth
(Elsevier, 2017)
We present a novel numerical method to simulate crack growth in 3D, directly from the Computer-Aided Design (CAD)
geometry of the component, without any mesh generation. The method is an isogeometric boundary element ...
