Solute strengthening in substitutional alloys can be classified into two categories, strong-pinning (Friedel) and weak-pinning (Labusch), each with its own characteristic scaling with concentration and temperature. The transition between the two strengthen ...
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 ...
Long term monitoring of structural elements of a 115 years old riveted railway bridge structure of high value as cultural heritage has been conducted. Monitored values were exploited by Rainflow analysis and served as the basis for the fatigue safety verif ...
This paper describes a macroscopic model of the chemo-thermo-poromechanical behaviour of a hydrating cement paste. The hydrating cement is viewed as an open hardening porous medium. The increments of elastic and viscoelastic strain, pore pressure, temperat ...
Cavitation erosion during the incubation period was investigated via pitting tests conducted on three different materials: an Aluminum alloy, a Nickel Aluminum Bronze alloy and a Duplex Stainless Steel. Pitting tests were conducted in a cavitation tunnel i ...
Alkali-Silica Reaction (ASR) is a deleterious expansion phenomenon which affects the long-term behaviour of concrete. Its origin is a chemical reaction between amorphous silica present in the aggregates and alkali ions from the concrete pore solution. The ...
We propose a finite element approximation of a system of partial differential equations describing the coupling between the propagation of electrical potential and large deformations of the cardiac tissue. The underlying mathematical model is based on the ...
Biological cells modulate their behavior, express genes, proliferate or differentiate in response to mechanical strains ranging from 1% to 20%. There currently exists no technique to apply strain to many targeted individual cells in a larger culture in ord ...
Digital image correlation (DIC) is assessed as a tool for measuring strains with high spatial resolution in woven-fiber ceramic matrix composites. Using results of mechanical tests on aluminum alloy specimens in various geometric configurations, guidelines ...
Alloys containing substitutional solutes exhibit strengthening due to favorable solute fluctuations within the alloy that hinder dislocation motion. Here, a quantitative, parameter-free model to predict the flow stress as a function of temperature and stra ...
