Atomistic simulation of the elongation response of a < 011 > oriented columnar nano-grain bcc Fe polycrystalline sample
The tensile elongation of an < 011 > oriented columnar nanocrystalline pure iron structure at a temperature of 300 K has been simulated by molecular dynamics (MD). The simulated sample contains 4.3 x 10(6) atoms and has been subject to free elongation alon ...
Springer2016Failure of mounting bolt of helicopter main gearbox support strut
The mounting bolt of helicopter main gearbox support strut was fractured into two pieces during the flight mission. The fracture occurred at the root of the first engaged thread of the bolt-nut assembly. Visual inspection of the fracture zone revealed crac ...
Elsevier2016Embrittlement induced by the synergistic effects of radiation damage and helium in structural steels
Ferritic/martensitic steels are candidate materials for fusion reactor structural components, liquid metal containers of spallation neutron sources, and accelerator driven systems, with good radiation resistance and thermo-mechanical properties. However, e ...
EPFL2015Microstructural characterizations of 14Cr ODS ferritic steels subjected to hot torsion
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 ...
Elsevier2015Probability of twin boundary formation associated with the nucleation of equiaxed grains on icosahedral quasicrystal templates
Recently, we have shown that minute Cr additions (typically 0.1 wt%) to Al-Zn alloys solidified in a uniform temperature field lead to the formation of fine equiaxed fcc Al grains [1]. Furthermore, these grains exhibit an unexpectedly large number of twin, ...
Iop Publishing Ltd2015Welding simulation of tubular K-joints in steel S690QH
Alain Nussbaumer, Jean-Marie Drezet, Farshid Zamiri Akhlaghi
Residual stress state in planar tubular K-joints, in the chord within the gap region between the two braces, is studied using numerical weld modelling. The motivation comes from past full-scale fatigue tests on tubular trusses made of various steel grades ...
CRC press2015Correlation between ferrite grain size, microstructure and tensile properties of 0.17wt% carbon steel with traces of microalloying elements
Five different grain sizes are produced in 0.17 wt% carbon steel using varying rates of cooling from austenitization temperatures. Controlled furnace cooling from 1100 °C and 950 °C produces coarse ferrite grains of 40 µm and 32 µm diameter, respectively, ...
Elsevier2014Size effect model for the edge strength of glass with cut and ground edge finishing
The edge strength of glass is influenced by the size of the surface (near the edge) which is subjected to tensile stresses. To quantify this size effect, 8 series of single layer annealed glass beam specimens (as-received glass) were subjected to in-plane ...
Elsevier2014Exploratory 2D and 3D numerical investigation of SG-laminated reinforced glass beams
SentryGlas®(SG)-laminated reinforced glass beams are numerically investigated. This innovative structural typology consists of a composite section in which the typical brittle behaviour of glass is overcome by means of stainless steel sections able to prov ...
2014Effects of grain size and gradation on the dynamic responses of quartz sands
The dynamic compression responses of quartz sands of different grain sizes and gradations are tested with a modified spilt Hopkinson pressure bar in which a single-pulse loading system is implemented. The yield stresses, the compressibility and the energy- ...
