Dislocation-void interaction in Fe: a comparison between molecular dynamics and dislocation dynamics

Multiscale modeling, including molecular dynamics (MD) and discrete dislocation dynamics (DDD) methods, appears as a signiﬁcant tool for the description of plasticity and mechanical properties of materials. This research concerns the inﬂuence of irradiatio ...

Dislocation-void interaction in Fe: a comparison between molecular dynamics and dislocation dynamics

Seyed Masood Hafez Haghighat

Multiscale modeling, including molecular dynamics (MD) and discrete dislocation dynamics (DDD) methods, appears as a significant tool for the description of plasticity and mechanical properties of materials. This research concerns the influence of irradiat ...

Modified atomic force microscopy cantilever design to facilitate access of higher modes of oscillation

Luis Guillermo Villanueva Torrijo

The detection of higher modes of oscillation in atomic force microscopy can provide additional information on sample properties. However, the limited bandwidth of the photodiode in the beam deflection detection technique often limits the detectable frequen ...

Large Eddy Simulation of turbulent compressible flow in heated curved square duct

Characteristics of turbulent flow and heat transfers which develop in a heated duct are studied through Large Eddy Simulation (LES) technics . Cooling channels of rocket engines constitute one of the industrial applications. We here consider a simplified g ...

Classical print reflection models: a radiometric approach

Roger Hersch, Mathieu Hébert

The present contribution reviews the classical print prediction models of Williams and Clapper and of Clapper and Yule by pursuing a radiometric approach. The relationship between these models is established and the related respective contributions of Judd ...

A new method to evaluate the fracture toughness of thin films

William Curtin

A method based on microindentation is developed to determine the fracture toughness K-1c of a thin film bonded to a brittle substrate. Using an easily fabricated sample having a partially coated substrate, indentation on the uncoated portion of the substra ...

Finite element method study of the coupling effect between superconducting filaments in varying magnetic field

Francesco Grilli, Yong Yang, Bertrand Dutoit

Using 3D finite element modelling, the present work investigates the coupling effect between superconducting filaments induced by an externally applied varying magnetic field. The considered geometry consists of two superconducting filaments separated by a ...

Spin interference and Fabry–Pérot resonances in ferromagnet–semiconductor–ferromagnet devices

Dirk Grundler

Magnetoconductance across permalloy/InAs(2DES)/permalloy double junctions in the ballistic limit is examined within the transfer-matrix formalism. We take into account Rashba spin–orbit interaction in the semiconductor as well as oblique modes in devices o ...

Mesh Optimization Using Global Error with Application to Geometry Simplification

Martin Vetterli, Thomas Liebling, Laurent Balmelli

Meshes with (recursive) subdivision connectivity, such as subdivision surfaces, are increasingly popular in computer graphics. They present several advantages over their Delaunay-type based counterparts, e.g., Triangulated Irregular Networks (TINs), such a ...

Geometry considerations for use of Bi-2223/Ag tapes and wires with different models of Jc(B)

Bertrand Dutoit

In typical power applications, Bi-2223 conductors carrying ac current will be subjected to external magnetic fields, whose orientation and conductor’s geometry are of major significance for the ac loss magnitude. This paper investigates the influence of th ...
