The efficiency of two coupling formulations, the boundary element method (BEM)-meshless local Petrov–Galerkin (MLPG) versus the BEM-finite element method (FEM), used to simulate the elastic wave propagation in fluid-filled boreholes generated by a blast load, is compared. The longitudinal geometry is assumed to be invariant in the axial...

The benefits of Project Based Learning (PBL) to acquire technological knowledge as well as transversal skills by students are well known. However, the implementation of PBL requires additional efforts from teachers and students, as well as additional teaching resources when compared to traditional teaching. This paper presents a case study of a...

This paper proposes a novel boundary element approach formulated on the Bézier–Bernstein basis to yield a geometry-independent field approximation. The proposed method is geometrically based on both computer aided design (CAD) and isogeometric analysis (IGA), but field variables are independently approximated from the geometry. This approach...

This paper proposes an enhancement of the treatment of non-homogeneous boundary conditions to improve the boundary element method (BEM) formulation. The standard formulation is modified by introducing the boundary conditions in the integral kernels. The boundary conditions are implicitly defined through known parameters depending on the...

En este artículo se presentan dos metodologías basadas en las formulaciones de los métodos de los elementos de contorno y de los elementos finitos para estudiar el efecto de la interacción suelo-estructura en el comportamiento dinámico de edificaciones. Se ha estudiado la respuesta de un edificio de tres plantas producida por un campo de ondas...

En este artíıculo se estudia la influencia de la interacción dinámica vehículo-vía-estructura-suelo en el comportamiento de viaductos. Dicho anáalisis se lleva a cabo usando un modelo acoplado, formulado en el dominio del tiempo, para predecir las vibraciones producidas por el paso de trenes. El vehículo se modeliza usando un sistema...

Este trabajo presenta los resultados de una experiencia de innovación docente dentro de la docencia en el ámbito de las estructuras en la titulación de Ingeniería Industrial en la Universidad de Sevilla. La metodología docente aplicada pretende motivar al alumno al aprendizaje promoviendo el diseño, cálculo, construcción y ensayo de...

This paper describes a general method to compute the boundary integral equation for common engineering problems. The proposed procedure consists of a new quadrature rule to evaluate singular and weakly singular integrals. The methodology is based on the computation of the quadrature weights by solving an undetermined system of equations in the...

In this paper, a general and fully three dimensional multi-body-finite element-boundary element model, formulated in the time domain to predict vibrations due to train passage at the vehicle, the track and the free field, is presented. The vehicle is modelled as a multi-body system and, therefore, the quasi-static and the dynamic excitation...

This paper presents the results of an innovative teaching experience in the area of structural analysis in the mechanical engineering program of the Universidad de Sevilla, Spain. The teaching methodology used is aimed at motivating students to learn by promoting the design, calculation, building, and testing of structures. This method not only...
