Model updating of a historical building by using ambient vibration tests : Chapel of the Würzburg Residence (Germany)
(Víctor Compán Cardiel [etc.], 2015)
One of the first difficulties that can be detected in finite element models of historical buildings is the high level of uncertainty associated with many factors affecting the actual behaviour of the structure. Often the ...

Análisis de postpandeo de un panel rigidizado de material compuesto mediante técnicas de modelado multi-global-local incluyendo daño interlaminar
(Asociación Española de Materiales Compuestos (AEMAC), 2015-07)
El uso de paneles rigidizados de material compuesto ha sido incorporado en numerosas aplicaciones. En las situaciones en las que las cargas originan estados tensionales de compresión, éstas pueden producir fenómenos de ...

Stress analysis of finite anisotropic plates with cutouts under displacement boundary conditions
(Asociación Española de Materiales Compuestos (AEMAC), 2015-07)
The aim of this article is to provide an analytical tool to estímate the stress concentration in anisotropic plates weakened by a circular or elliptical hole; it is achieved by developing Lekhnitskii formalism in order ...

Self-control of a lively footbridge under pedestrian flow
(Víctor Compán Cardiel [etc.], 2015)
In this paper, a case study about a lively footbridge is developed; the vibration levels caused by the pedestrian action are controlled by the change of the modal parameters of the structure due to the pedestrian-structure ...

Influence of micromechanics in composite panels buckling loads
(Víctor Compán Cardiel [etc.], 2015)
In-plane compression loads may cause buckling of fiber-reinforced composite panels. An accurate knowledge of these critical buckling loads is essential for structural design. In all cases of buckling of panels, critical ...

Manufacturing and testing of a cruciform coupon for biaxial transverse tests
(International Committee on Composite Materials, 2015)
The present study deals with the manufacturing of cruciform coupons to be tested under tensile biaxial transverse loads. The objective is to obtain a geometry that minimizes the effect of stress concentrations, maximizes ...

Semi-analytic solution on non-regularized unfolding stress in composite beams employing a series approximation based on legendre polynomilas
(2015)
Unfolding is one of the main causes of failure on composite beams including curved parts in their sections, such as L-beams, T-beams or C-beams, it being in many cases the critical criterion in the sizing of this kind of ...

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 ...
