Soil-structure interaction in resonant railway bridges
(Elsevier, 2013)
This paper explores dynamic soil–bridge interaction in high speed railway lines. The analysis was conducted using a general and fully three-dimensional multi-body finite element–boundary element model formulated in the ...

Ballast shear effects on the dynamic response of railway bridges
(Elsevier, 2022-12-01)
Single-track railway bridges are susceptible of experiencing high levels of vertical acceleration on the deck that may be dangerously accentuated at resonance. This is especially critical for short-to-medium span simply ...

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 ...

Influence of Materials of Moulds and Geometry of Specimens on Mechanical Properties of Grouts Based on Ultrafine Hydraulic Binder
(MDPI, 2024-04)
Ultrafine hydraulic binder grout injection is a technique utilised for repairing masonry, either to connect sections, seal joints, or fill voids due to its great capacity for penetration and higher mechanical strength than ...

Determination of Generalized Fracture Toughness in composite multimaterial closed corners with two singular terms - Part I: Test proposal and numerical analysis
(Elsevier, 2012-07)
In the present work a general procedure for the experimental evaluation of Generalized-Fracture-Toughness values at multimaterial closed corners is defined. The lack of symmetries in the stress fields at multimaterial ...

Determination of Generalized Fracture Toughness in composite multimaterial closed corners with two singular terms - Part II: Experimental results
(Elsevier, 2012-07)
In this paper the experimental part of the procedure for the Generalized-Fracture-Toughness determination in multimaterial closed corners with two stress singularities is presented. The so-called Generalized-Fracture-Toughness ...

Influence of graphene oxide concentration and ultrasonication energy on fracture behavior of nano-reinforced cement pastes
(MDPI, 2024-08-05)
The aim of this study is twofold. First, to assess the effect of the sonication process on the optimal dispersion of GO sheets for nanostructural reinforcement of cement pastes, as there is currently no clear criterion on ...

Closed-form expressions for computing flexoelectric coefficients in textured polycrystalline dielectrics
(Elsevier, 2024-01)
The volume average of the constituting properties of a textured polycrystalline aggregate (the Voigt average) provides a simple way to estimate the effective properties of such an aggregate in terms of its crystallographic ...
