ITER Central Solenoid Insert Test Results

The ITER central solenoid (CS) is a highly stressed magnet that must provide 30 000 plasma cycles under the ITER prescribed maximum operating conditions. To verify the performance of the ITER CS conductor in conditions close to those for the ITER CS, the C ...

Delamination monitoring using low frequency stress waves for laminated composites

Wei Shi, Zhisheng Yang, Pingyu Zhu

Owing to the anisotropy of composite laminates, local responses happens at periphery of the drilled hole even under the same loads. The strain measurement is probably the most sensitive and better option to detect and quantify delamination inside composite ...

Microstructural characterizations of 14Cr ODS ferritic steels subjected to hot torsion

Roland Logé

Oxide dispersion strengthened (ODS) steels are very promising materials for nuclear applications. In thispaper, the hot working behavior of ODS ferritic steels, consolidated by hot extrusion, is studied through torsion tests. Three ODS steels are produced ...

A mean field model of dynamic and post-dynamic recrystallization predicting kinetics, grain size and flow stress

Roland Logé, Ke Huang

A physically-based two-site mean field model has been developed to describe the microstructural evolution due to recrystallization during and after deformation. The model has been applied to predict the recrystallized fraction, recrystallized grain size, a ...

Pressure-Driven Suspension Flow near Jamming

Brice Tanguy Alphonse Lecampion, Dmitriy Garagash

We report here magnetic resonance imaging measurements performed on suspensions with a bulk solid volume fraction (φ0) up to 0.55 flowing in a pipe. We visualize and quantify spatial distributions of φ and velocity across the pipe at different axial positi ...

Analogy between Sustained Loading and Strain Rate Effects on the Nonlinear Creep Response of Concrete

Aurelio Muttoni, Miguel Fernández Ruiz, Darko Tasevski

This paper investigates the uniaxial compression behaviour of concrete under different strain rates and its relation to sustained loading. The aim is to observe the strain rate effect on the pre- and post-peak behaviour of concrete. In particular, the deve ...

Stress-accurate Mixed FEM for soil failure under shallow foundations involving strain localization in plasticity

Lorenzo Benedetti

The development of slip lines, due to strain localization, is a common cause for failure of soil in many circumstances investigated in geotechnical engineering. Through the use of numerical methods – like finite elements – many practitioners are able to ta ...

Ductile flow in sub-volcanic carbonate basement as the main control for edifice stability: New experimental insights

Marie Estelle Solange Violay

Limestone in volcanic basements has been identified as a hazard in terms of edifice stability due to the propensity of calcite to decompose into lime and CO2 at high temperatures (>600 °C), causing a decrease in mechanical strength. To date, such hypoth ...

Laminated Connections for Structural Glass Applications

Manuel Santarsiero

The demand for architectural transparency has drastically increased structural use of glass in buildings and constructions. Connections between structural glass components represent one of the main critical aspects of glass engineering. In the last years, ...

Exciton hopping probed by picosecond time-resolved cathodoluminescence

Benoît Marie Joseph Deveaud, Jean-Daniel Ganière, Gwénolé Jean Jacopin, Mehran Shahmohammadi

The exciton transport is studied in high quality ZnO microwires using time resolved cathodoluminescence. Owing to the available picosecond temporal and nanometer spatial resolution, a direct estimation of the exciton average speed has been measured. When r ...
