Finite element modeling of the WC-10 wt.% Co thermal stresses: Build-up and phase specific strain response during cyclic loading

Several finite element models of the morphology of WC-10 wt.% Co were employed to reproduce the build-up of thermal residual stresses as well as the phase specific strain during loading-unloading in compression. The different models differ only in their ge ...

Block and variable amplitude fatigue and fracture behavior of adhesively-bonded composite structural joints

Anastasios Vassilopoulos

The fatigue behavior of adhesively-bonded glass fiber-reinforced polymer (GFRP) joints is affected by the loading sequence. Analysis of several experimental data for composite materials and adhesively-bonded composite joints showed that the loading sequenc ...

NEUTRON DIFFRACTION MEASUREMENT OF AS-CAST RESIDUAL STRESSES IN AA7050 ROLLING PLATE INGOTS: INFLUENCE OF A WIPER

Jean-Marie Drezet

During casting, thermally induced deformations give birth to ingot distortions and residual stresses. For some high strength alloys, ingot cracking can happen during casting per se or during cooling down. Ingot distortions such as rolling face pull-in, but ...

Modelling of fatigue behaviour of bridge deck slab elements strengthened with reinforced UHPFRC

Tohru Makita

With the occurrence of higher and more frequent axle loads on roads, in particular bridge deck slabs are more severely solicitated by fatigue loading. To avoid heavy interventions for strengthening of deck slabs, an improved building material is used, name ...

Tensile fatigue behaviour of Ultra-High Performance Fibre Reinforced Concrete combined with steel rebars (R-UHPFRC)

Eugen Brühwiler, Tohru Makita

Ultra-High Performance Fibre Reinforced Concrete (UHPFRC) combined with steel rebars, subsequently called R-UHPFRC, is a promising building material implying a novel technology for the improvement of concrete structures. Steel rebars enhance effectively th ...

Numerical modelling and experimental investigation on welding residual stresses in large-scale tubular K-joints

Alain Nussbaumer, Jean-Marie Drezet, Claire Acevedo

This paper is devoted to the experimental and numerical assessment of residual stresses created by welding in the region surrounding the weld toe of tubular K-shaped joints (i.e. region most sensitive to fatigue cracking). Neutron-diffraction measurements ...

Alternative stress definition and residual stress effects in fatigue design of welded tubular structures

Alain Nussbaumer, Claire Acevedo, Luís Costa Borges, Farshid Zamiri Akhlaghi

Steel tubular truss are lightweight, aesthetical and used in many different applications. These structures are sensitive to fatigue and specific verification methods have been developed for them, in particular by CIDECT [2001]. Due to assembly and welding, ...

Residual stress and pinch contributions to momentum transport in JET neutral beam heated H-modes

Henri Weisen, Yann Camenen

NA broad survey of the experimental database of neutral beam heated baseline and hybrid scenarios in the JET tokamak with the C-wall was undertaken and has established the ubiquity of non-diffusive momentum transport mechanisms in externally driven, strong ...

Finite element modeling for fatigue strengthening of metallic riveted bridges using un-bonded pre-stressed CFRP plates

Alain Nussbaumer, Gary Scott Prinz, Andrin Herwig, Mario Fontana, Elyas Ghafoori

Many old riveted steel bridges remain operational and require retrofit to accommodate ever increasing demands. Complicating retrofit efforts, riveted steel bridges are often considered historical structures and as such structural modifications that affect ...
