Game theory-based maximum likelihood method for finite-element-model updating of civil engineering structures
(Elsevier, 2023)
Finite element modelling is performed to numerically predict the behaviour of civil engineering structures. Due to the different assumptions adopted during the modelling phase, this initial model does not always ...

The effect of ballast moisture content and fouling index on railway track settlement
(Elsevier, 2024-03)
A primary function of railway ballast is to maintain vertical track geometry, however over time it becomes contaminated with fines which reduce its ability to free-drain. Then, in the presence of moisture, the individual ...

Estados singulares de tensión en esquinas multimateriales
(Grupo Español de Fractura, 2007)
La unión entre materiales de distinta naturaleza genera puntos críticos en la estructura donde aparecen cambios bruscos en la geometría y propiedades de los materiales (esquinas multimateriales). La teoría de la Elasticidad ...

Prediction of welding residual stresses and displacements by simplified models. Experimental validation
(Elsevier, 2010-03)
Numerical simulations of welding processes are complex and computationally expensive. Several simplificative hypotheses are typically used in the simulations for time saving considerations, some of which have been explored ...

A new crack-tip element for the logarithmic stress-singularity of Mode-III cracks in spring interfaces
(Springer, 2024-02)
A new crack-tip finite element able to improve the accuracy of Finite Element Method (FEM) solutions for cracks growing along the Winkler-type spring interfaces between linear elastic adherents is proposed. The spring model ...

Fatigue crack initiation and damage characterization in Brazilian test specimens for adhesive joints
(Taylor & Francis, 2014)
The present study is focused on the fatigue failure initiation at bimaterial corners by means of a configuration based on the Brazilian disc specimens. These specimens were previously used for the generalized fracture ...

Evaluation of the stiffnesses of the Achilles tendon and soleus from the apparent stiffness of the triceps surae
(SAGE, 2015-01)
The triceps surae plays an important role in the performance of many sports. Although the apparent average mechanical properties of the triceps surae may be a satisfactory parameter for estimating the training level of an ...

El método de los elementos de contorno aplicado al cálculo de placas apoyadas
(Asociación Española de Ingeniería Mecánica, 1982-12)
Se analiza el problema de placas elásticas apoyadas , sometidas a carga estática mediante una formulación integral obtenida a partir de la des composición de la ecuación biarmónica que rige el comportamiento de dichas ...

CNT-polymer nanocomposites under frictional contact conditions
(Elsevier, 2018-12)
The unique intrinsic physical properties of Carbon NanoTubes (CNTs) suggest that they are ideal fillers for high-performance composites. Although some experimental studies have revealed the potential of these nanoparticles ...

Exploring the impact of graphene oxide on mechanical and durability properties of mortars incorporating demolition waste: micro and nano-pore structure effects
(Consejo Superior de Investigaciones Científicas, 2023-12)
In this study is explored the use of construction and demolition waste as fine aggregate in mortars. The addition of nano-graphene oxide (0.1%wt) has also been evaluated. Tests were conducted to determine their density, ...
