Resumen en español El uso del ensayo edométrico para determinar la respuesta volumétrica de muestras de suelo data de los orígenes de la mecánica de suelos. Por lo general, el uso del ensayo ha estado enmarcado en el estudio de muestras naturales talladas en anillos de pared delgada, sin generar un estado de esfuerzos iniciales que perturbe la respuesta volumétrica del material. Sin embargo, en el marco del estudio del comportamiento de barreras de arcilla para el aislamiento de desech (mas) os nucleares se presenta la necesidad de ensayar materiales expansivos altamente compactados, por lo que este ensayo se ha estado utilizando con muestras compactadas directamente en el anillo edométrico, introduciendo un estado inicial de esfuerzos que afecta la respuesta volumétrica del material por efectos de roce lateral. En este artículo se presentan resultados de ensayos de hidratación, sobre muestras de una arcilla expansiva compactada, realizados para mostrar dichos efectos y que permiten mostrar la importancia del protocolo de preparación de las muestras, lo cual es el objetivo principal de este trabajo. Resumen en inglés The use of oedometer test to determine the volumetric response of soil samples dates from the beginnings of soil mechanics. Currently, the use of the test has been focused in the study of natural samples that are trimmed in thin wall rings, which do not generate initial stress states that could perturb the volumetric response of the sample. However, due to the increasing interest in studing highly compacted swelling soils, in the case of engineered barriers for nuclear wa (mas) ste disposal, this test has been conducted on samples directly compacted in the oedometer ring. This practice introduces an initial stress state that affects the volumetric response due to frictional effects. In this paper, some results of hydration tests on compacted swelling clay are presented to point out such effects, permitting to show the relevance of the way the samples are prepared, which is the goal of this work.

Un método de acople para mef - mec para análisis de interacción suelo - estructura/ A fem-bem coupling method for soil - structure interaction analysis

Resumen en español El Método de los Elementos Finitos y el Método de los Elementos de Contorno son las herramientas numéricas más utilizadas para análisis en mecánica de sólidos. Cada uno de estos métodos tiene sus ventajas y desventajas en diferentes casos. El MEF es adecuado para análisis de dominios finitos con materiales no homogeneos y comportamiento no lineal, mientras que MEC ofrece ventajas en el análisis de dominios infinitos con materiales homogéneos y comportamiento li (mas) neal. En este trabajo se presenta un acople iterativo del método de los elementos finitos y el método de los elementos de contorno. El dominio del problema es dividido en dos subdominios, donde cada subdominio es analizado por separado y sólo la información en la interfase es comunicada entre los dos subdominios. El ensamble y análisis de un sistema de ecuaciones general es evitado, obteniéndose ventaja de las características de las matrices, ya que el sistema de ecuaciones en el método de los elementos finitos es simétrico.Los resultados numéricos obtenidos concuerdan satisfactoriamente con resultados obtenidos por otros autores. Resumen en inglés The Finite Element Method and the Boundary Element Method are the most used numerical tools for solid mechanics analysis. Each one of these methods has advantages and drawbacks in different cases. FEM is well suited for finite domains with inhomogeneous materials and non linear behaviour while BEM offers advantages when dealing with infinite domains displaying homogeneous materials and linear behaviour. An iterative coupling of the Finite Element Method and the Boundary E (mas) lement Method is presented. The domain of the problem is divided in two subdomains, where each subdomain is analyzed separately and only the interface information is exchanged between both subdomains. The assembly and solution of a general equation system is avoided, thus obtaining full advantage of the matrices characteristics, since the system of equations is symmetric in FEM. Numerical results compare well with other available numerical results.
