A 2.5D coupled FE-BE model for the prediction of railway induced vibrations
(Elsevier, 2010)
Ground vibrations induced by railway traffic at grade and in tunnels are often studied by means of two-and-half dimensional (2.5D) models that are based on a Fourier transform of the coordinate in the longitudinal direction ...

Mesoscale Characterization of Fracture Properties of Steel Fiber-Reinforced Concrete Using a Lattice–Particle Model
(MDPI, 2017-02-21)
This work presents a lattice–particle model for the analysis of steel fiber-reinforced concrete (SFRC). In this approach, fibers are explicitly modeled and connected to the concrete matrix lattice via interface elements. ...

Concurrently coupled solid shell-based adaptive multiscale method for fracture
(Elsevier, 2017-06)
A solid shell-based adaptive atomistic–continuum numerical method is herein proposed to simulate complex crack growth patterns in thin-walled structures. A hybrid solid shell formulation relying on the combined use of the ...

Motion-Based Design of Passive Damping Devices to Mitigate Wind-Induced Vibrations in Stay Cables
(MDPI, 2018-11)
Wind action can induce large amplitude vibrations in the stay cables of bridges. To reduce the vibration level of these structural elements, different types of passive damping devices are usually installed. In this paper, ...

Phase field modeling of brittle fracture in large-deformation solid shells with the efficient quasi-Newton solution and global–local approach
(Elsevier, 2022)
To efficiently predict the crack propagation in thin-walled structures, a global–local approach for phase field modeling using large-deformation solid shell finite elements considering the enhanced assumed strain (EAS) and ...

Reliability analysis of Solar-Gas Hybrid Receivers for central tower plants
(Elsevier, 2015)
A novel Solar-Gas Hybrid Receiver (SGHR) that combines the function of a solar receiver and a gas boiler in a single device is presented. This concept requires less equipment and maintenance compared to the Solar Gas ...

Sobre el uso de dispositivos de mordazas giratorias en el ensayo off-axis
(AEMAC (Asociación Española de Materiales Compuestos), 1999)
El ensayo de tracción "off-axis" es uno de los medios más simples para la evaluación del módulo de cortadura intralaminar en laminados unidireccionales, sin embargo es bien conocido que su realización práctica conlleva ...

Recent developments in the evaluation of the 3D fundamental solution and its derivatives for transversely isotropic elastic materials
(2012)
Explicit closed-form real-variable expressions of a fundamental solution and its derivatives for three-dimensional problems in transversely linear elastic isotropic solids are presented. The expressions of the fundamental ...
