Modeling elastic wave propagation in fluid-filled boreholes drilled in nonhomogeneous media: BEM – MLPG versus BEM-FEM coupling
(Elsevier, 2017)
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 ...

Damage localization and quanti cation in simply supported beams using static test data
(IOP Publishing, 2017)
A novel simple method using static test data for damage detection, localization, and quanti cation in beams is presented in this paper. The method is based on the change of the de ections of the beam between a reference ...

Numerical analysis of the influence of a nearby fibre on the interface crack growth in composites under transverse tensile load
(European Structural Integrity Society, 2016)
In this paper the interface crack growth associated to the inter-fibre failure under tension is studied by means of a two-fibres BEM model. The influence of the presence of an undamaged secondary fibre on the evolution ...

Effect of mix design on the size-independent fracture energy of normal- and high-strength self-compacting concrete
(Consejo Superior de Investigaciones Científicas (CSIC), 2018-02)
Self-compacting concrete has a characteristic microstructure inherent to its specific composition. The higher content of fine particles in self-compacting concrete relative to the equivalent vibrated concrete produces a ...

Continuous wavelet analysis of mode shapes differences for damage detection
(Elsevier, 2013)
This paper presents a new damage detection methodology for beams. It applies wavelet analysis to locate the damage from changes in the mode shapes (geometric based analysis). The proposed methodology requires the mode ...
