Experimental validation of usual numerical models of cracked beams for damage detection approaches
(Víctor Compán Cardiel [etc.], 2015)
The performances of damage detection approaches are often tested by using numerical solutions of undamaged and damaged structures. However, the numerical results used for a preliminary analysis are useful as far as they ...

Estudio experimental de placas preconformadas en postpandeo
(Asociación Española de Materiales Compuestos (AEMAC), 2015-07)
El pandeo de placas y láminas no necesariamente está asociado al colapso, que en ocasiones se produce para una carga que es varias veces superior. No obstante, aprovechar esta capacidad postpandeo no es fácil, siendo el ...

Análisis de postpandeo de un panel rigidizado de material compuesto sometido a carga de presión
(AEMAC (Asociación Española de Materiales Compuestos), 2011)
Para predecir el comportamiento de un panel curvo rigidizado ante una carga de presión por encima de la carga de pandeo se han realizado varias simulaciones numéricas con ABAQUS/Standard. Dada la influencia que las ...

A 2.5D BEM-FEM using a spectral approach to study scattered waves in fluid–solid interaction problems
(WITPress, 2019)
This work presents a two-and-a-half dimensional (2.5D) spectral formulation based on the finite element method (FEM) and the boundary element method (BEM) to study wave propagation in acoustic and elastic waveguides. The ...

Estimating robust optimum parameters of tuned mass dampers using multiobjective genetic algorithms
(Víctor Compán Cardiel [etc.], 2015)
Tuned mass dampers (TMD) are a well-known control device widely used to control the vibratory problem originated by the pedestrian action on footbridges. The main purpose of this study is the robust multi-objective ...

Device for biaxial testing in uniaxial machines. Design, manufacturing and experimental results using cruciform specimens of composite materials
(Asociación Española de Materiales Compuestos (AEMAC), 2013-07)
The present work deals with the design and manufacturing of a mechanical device to perform biaxial testing in universal (uniaxial) testing machines. A review of previous similar proposals is carried out and a new ...

Scoping methodology to asses induced vibration by railway traffic in buildings
(Elsevier, 2017)
This work presents a scoping model to predict ground-borne railway vibration levels within buildings considering soil-structure interaction (SSI). It can predict the response of arbitrarily complex buildings in a fraction ...

Analysis of stationary roving mass effect for damage detection in beams using wavelet analysis of mode shapes
(IOPscience, 2015)
One of the main challenges in damage detection techniques is sensitivity to damage. During the last years, a large number of papers have used wavelet analysis as a sensitive mathematical tool for identifying changes in ...
