Modelling of acoustic and elastic wave propagation from underground structures using a 2.5D BEM-FEM approach
(Elsevier, 2017-03)
This paper presents a numerical method based on a two-and-a-half dimensional (2.5D) boundary element-finite element (BEM-FEM) coupled formulation to study noise and vibration from underground structures. The proposed model ...

A Finite Element‑Based Methodology for the Thermo‑mechanical Analysis of Early Age Behavior in Concrete Structures
(SpringerOpen, 2019)
This paper presents a general procedure based on fracture mechanics models in order to analyze the level of cracking and structural safety in reinforced concrete elements at early ages, depending on the stripping time. ...

A new in situ peeling test for the characterisation of composite bonded joints
(Elsevier, 2018-10)
At the moment, bonded joints quality on composites used in aeronautical industry is verified based on the determination of the interlaminar fracture toughness (Gc) obtained by means of the Double Cantilever Beam (DCB) or ...

On the basic phenomenon of soil-structure interaction on the free vibration response of beams: application to railway bridges
(Elsevier, 2016)
The dynamic transverse response of beam type bridges under railway tra c is addressed in this contribution. In particular, how soil-structure interaction may a ect the critical or resonant speeds and the associated vibratory ...

Quantification of uncertainty in the prediction of railway induced ground vibration due to the use of statistical track unevenness data
(Elsevier, 2014)
Environmental vibrations due to railway traffic are predominantly due to dynamic axle loads caused by wheel and track unevenness and impact excitation by rail joints and wheel flats. Because of its irregular character, ...

Dynamic characterisation of wind turbine towers account for a monopile foundation and different soil conditions
(Taylor & Francis (Routledge), 2017)
The response of wind turbines is induced by dynamic loads such as wind, transient and cyclic loads, and also extreme loads such as earthquakes. Thus, the structural design requires an accurate evaluation of the modal ...

Experimental study of the size effect on transverse cracking in cross-ply laminates and comparison with the main theoretical models
(Elsevier, 2019-01)
Transverse cracking of off-axis plies is typically the first step of some failure mechanisms in long fiber reinforced laminated composites. It is well known that the off-axis ply thickness affects strongly the strain level ...
