SAMARIS D26 - Modelling of UHPFRC in composite structures

The extremely low permeability of Ultra-High Performance Fibre Reinforced Concretes (UHPFRC) associated with their outstanding mechanical properties make them especially suitable to locally "harden" reinforced concrete structures in critical zones subjecte ...

Residual stress characterization in a single fibre composite specimen by using FBG sensor and the OLCR technique

Fabiano Colpo

The purpose of this thesis is to characterize internal strains in polymeric materials due to consolidation. In view of this, optical Fiber Bragg Grating sensors are an excellent non-destructive tool for internal strain characterization and damage detection ...

Damage and fracture of particle-reinforced metal matrix composites

Andreas Mortensen, Andreas Rossoll, Aude Hauert

Particle Reinforced Metal Matrix Composites (PRMMCs) are produced by high-pressure infiltration of ceramic particle beds. Matrix materials are either pure Al or Al-4,5%Cu, and the reinforcement is made either of angular or of polygonal alumina particles. T ...

Buckling and ultimate strength assessment of FPSO structures

Jamie Paik, Haomin Sun, Xiao Wang

Floating production, storage and offloading systems (FPSOs) have been widely used for the development of offshore oil and gas fields because of their attractive features. They are mostly ship-shaped, either converted from existing tankers or purposely buil ...

MEASUREMENT AND MODELLING OF FIBRE DISTRIBUTION AND ORIENTATION IN UHPFRC

Eugen Brühwiler, Emmanuel Denarié, John Wuest

Ultra High Performance Fibre Reinforced Concretes (UHPFRC) combine outstanding protective (extremely low permeability) and mechanical (high tensile strength and significant tensile strain hardening) properties. These materials can be used in composite UHPF ...

On the strain-hardening of tempered martensitic alloys

Philippe Spätig, Raul Alejandro Bonadé

The strain-hardening behaviour of a tempered martensitic iron-chromium-carbon model was examined in terms of dislocation mechanics. Tensile tests of this body-centered cubic alloy were carried out from 77 up to 293 K. A specific relationship between the fl ...

Adhesively bonded lap joints from pultruded GFRP profiles. Part II: joint strength prediction

Thomas Keller, Till Vallée

A method to predict the strength of adhesively bonded single and double lap joints from pultruded GFRP composite adherends subjected to quasi-static axial tensile loading is presented. The method is based on a quadratic through- thickness shear-tensile int ...

Plastic deformation mechanisms in nanocrystalline columnar grain structures

William Curtin

We present an atomistic study of the plastic deformation mechanisms occurring in columnar structures of nanocrystalline Ni, with particular emphasis on the process of dislocation emission form the grain boundaries. The samples are constructed with grain bo ...

Tensile properties of a tempered martensitic iron-chromium- carbon model alloy

Philippe Spätig, Raul Alejandro Bonadé

A detailed study of the strain-hardening on a Fe-9Cr-0.1C tempered martensitic model alloy has been undertaken in the temperature range of 77-343 K. The true stress-true strain curves were calculated from tensile test data. In the framework of a phenomenol ...

Assessment of the constitutive properties from small ball punch test: experiment and modeling

Philippe Spätig, Raul Alejandro Bonadé, Emiliano Campitelli

An assessment of the true stress-true strain relationship has been done by means of tensile and small ball punch tests on austenitic and tempered martensitic steel at room temperature. A finite element model was developed and validated to calculate the for ...
