Cold stiffening of orthotropic steel decks by a composite UHPFRC layer

Cold stiffening of the plate of Orthotropic Steel Deck (OSD) of bridges can be achieved by adding a layer of Ultra-High Performance Fiber Reinforced Cementitious Composite material (UHPFRC) on top of the deck plate by composite design, thus expecting to re ...

Influence of the stacking sequence on the low-energy impact resistance of flax/PA11 composite

Yann Albert Gérard Lebaupin

In this paper, the low-energy impact behavior of a fully biobased composite made of bio-sourced polyamide 11 resin reinforced with flax fibers was investigated. Different composite laminates were studied in order to determine the stacking sequence effects ...

Fast and accurate elastic analysis of laminated composite plates via isogeometric collocation and an equilibrium-based stress recovery approach

Pablo Antolin Sanchez, Alessandro Reali

A novel approach which combines isogeometric collocation and an equilibrium-based stress recovery technique is applied to analyze laminated composite plates. Isogeometric collocation is an appealing strong form alternative to standard Galerkin approaches, ...

Behavior of prestressed CFRP plates bonded to steel substrate: Numerical modeling and experimental validation

Ardalan Hosseini, Masoud Motavalli, Elyas Ghafoori

In recent years, retrofitting of steel structures has emerged as a major issue in structural engineering and construction management. As the adhesive bond is often the critical aspect controlling the actual performance of steel profiles externally strength ...

A cost-effective isogeometric approach for composite plates based on a stress recovery procedure

Pablo Antolin Sanchez, Alessandro Reali

This paper introduces a cost-effective strategy to simulate the behavior of laminated plates by means of isogeometric 3D solid elements. Exploiting the high continuity of spline functions and their properties, a proper out-of-plane stress state is recovere ...

Ultra high performance fiber reinforced concrete for strengthening and protecting bridge deck slabs

Eugen Brühwiler, Maléna Bastien Masse

An original concept is presented for the durable rehabilitation of concrete bridge deck slabs. The main idea is to add a layer of Ultra-High Performance Fiber Reinforced Concrete (UHPFRC) with or without steel reinforcing bars over the concrete slab to cre ...

Recent progress in research on tungsten materials for nuclear fusion applications in Europe

Nadine Baluc, Ho Ling Li, Lyubomira Veleva, Antoine Cyril David Hoffmann

The current magnetic confinement nuclear fusion power reactor concepts going beyond ITER are based on assumptions about the availability of materials with extreme mechanical, heat, and neutron load capacity. In Europe, the development of such structural an ...

Characterisation of Low Impact Energy Induced Damage in Composite Plates with Embedded Optical Sensors

Jeannot Frieden

Fibre reinforced materials are increasingly employed in aerospace, naval and civil structures because of their low weight and high specific strength and stiffness. A major concern is the inherent susceptibility of composite laminates to barely visible dama ...

On the insulator-conductor transition in polymer nanocomposites

Gianluca Ambrosetti

This thesis presents an investigation of the models describing electrical conductivity in polymer nanocomposites, which consist in more or less random dispersions of nanometric conductive fillers like carbon nanotubes, nanofibers or graphene sheets in a po ...

Structural Response of Reinforced UHPFRC and RC Composite Members

Cornelius Oesterlee

Ultra High-Performance Fibre-Reinforced Concrete (UHPFRC) combines high strength, deformation capacity and low permeability. This makes UHPFRC particularly suitable as a strengthening and protective layer for application to existing reinforced concrete str ...
