Lagrangian and ALE Formulations For Soil Structure Coupling with Explosive Detonation
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017)
Simulation of Soil-Structure Interaction becomes more and more the focus
of computational engineering in civil and mechanical engineering, where
FEM (Finite element Methods) for soil and structural mechanics and Finite
Volume for CFD (Computational Fluid Dynamics) are dominant. New
advanced formulations have been developed for FSI (Fluid Structure
Interaction) applications using ALE (Arbitrary ...
Numerical simulation of the dynamic response in pulse-loaded fibre–metal-laminated plates
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-07-27)
This article presents a three-dimensional constitutive model to replicate the dynamic response of blast-loaded fibre–metal laminates made of 2024-0 aluminium alloy and woven composite (glass fibre–reinforced polypropylene). Simulation of the dynamic response is challenging when extreme localised loads are of concern and requires reliable material constitutive models as well as accurate modelling ...
Design of water shock tube for testing shell materials
(Journal article; Tidsskriftartikkel; Peer reviewed, 2014-04-15)
This paper presents design considerations for a shock tube experimental rig used to investigate
the dynamic failure mechanisms of shell geometries subjected to water shock impact loading. In such setup, it is desirable that the drive pressure used within the tube can provide a wide range of impulsive loads on the test structures and some flexibility can be achieved on the applied pulse durations. ...

Numerical investigation of vibration and dynamic pressure of a vertical axis wind turbine
(Journal article; Tidsskriftartikkel; Peer reviewed, 2014-12-31)
In the environmental field, the problems of vibration reduction have become a major preoccupation, particularly on the noise generated by the acoustic radiation pressure produced by wind turbines. This paper is aimed at presenting the investigation on the application of FEM element method for study the acoustic radiation pressure produced by vertical-axis wind turbine. For this initiative, we ...
Deployment of a Neo-Hookean membrane: experimental and numerical analysis
(Journal article; Tidsskriftartikkel; Peer reviewed, 2013-03-31)
The aim of this research is to assess the response of a thin membrane subjected to high-pressure gas loading for inflation. This procedure is applied during the design process of the membrane structure to allow the product to resist high-pressure loading and to further characterize the hyper-elastic material. The simulation in this work considers the standard procedures used in the LS-DYNA software, ...
Fluid-structure Interaction for Water Hammers Effects in Petroleum and Nuclear Plants
(Journal article; Tidsskriftartikkel; Peer reviewed, 2011-12-31)
Fluid-Structure Interaction (FSI) becomes more and more the focus of
computational engineering in Petroleum and Nuclear Industry in the last years.
These problems are computer time consuming and require new stable
and accurate coupling algorithms to be solved. For the last decades, the
new development of coupling algorithms, and the increasing of computer
performance have allowed to solve some ...
