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 ...

Preserving the Great Mosque of Córdoba (Spain): characterization of natural stone based on rebound hammer and ultrasonic tests
(MDPI, 2023-10-24)
The preservation of The Great Mosque of Córdoba (Spain) as a carrier of Andalusian collective memory requires innovative approaches to assess and maintain its structural health. This research centers on two non-destructive ...

A finite element implementation of phase-field approach of fracture for nonlinear solid shells including inelastic material behavior
(ELSEVIER, 2024)
The parametrization of shell structures using the so-called solid shell concept has been widely exploited in the last decades. This trend is mainly attributed to the relatively simple kinematic treatment of solid shells ...

Characterization of Low-Velocity Impact Damage in Asymmetric Composite Shells
(Shahid Chamran University of Ahvaz, 2024)
Based on numerical modelling, this study investigates asymmetric semicylindrical composite laminate shells' damage characteristics under low-velocity impact loads. For this purpose, several asymmetric stacking sequences ...

A phase-field fracture model for fatigue using locking-free solid shell finite elements: Analysis for homogeneous materials and layered composites
(Elsevier, 2023-10)
A computational framework to model fatigue fracture in structures based on the phase-field method and the solid-shell concept is herein presented. With the aim of achieving a locking free solid-shell finite element formulation ...

Static and fatigue performance of non-circular rivet joints: Comparison between numerical modelling and preliminary testing
(Elsevier, 2024)
Alternative non-circular rivet joint geometries are investigated. An optimum non-circular rivet geometry based on a continuous change in the radius of curvature is proposed to minimise the stress concentration factor ...

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 ...
