PhD position(s) is available for Spring 2022 in the Engineering Mechanics program in Aerospace Engineering Department at Iowa State University to perform theoretical and computational part of work on NSF-funded projects on the interaction between phase transformations and plasticity. Phase-field, micromechanical, and macroscale simulations using FEM are of interest, in close collaboration with high-pressure experiments performed in our lab. Please send vita to Prof.

Abstract

Mode-coupling instabilities are known to trigger self-excited vibrations in sliding contacts. Here, the conditions for mode-coupling (or "flutter") instability in the contact between a spherical oscillator and a moving viscoelastic substrate are studied. The work extends the classical 2-Degrees-Of-Freedom conveyor belt model and accounts for viscoelastic dissipation in the substrate, adhesive friction at the interface and non-linear normal contact stiffness as derived from numerical simulations based on a boundary element method capable of accounting for linear viscoelastic effects.

Dear Colleagues,

The next edition of the European Mechanics of Materials Conference (EMMC18) will be held in Oxford, UK, on April 4-6, 2022:

EMMC18 is organised by the Department of Engineering Science of the University of Oxford, under the auspices of the European Mechanics Society, EUROMECH. The conference will take place in the Examinations Schools, in the heart of Oxford. 

We are delighted to announce the 11^th European Solid Mechanics Conference that will be held at the National University of Ireland Galway, in the city of Galway, Ireland, 4 – 8 July, 2022. The conference website is: www.esmc2022.org. The conference is being held under the auspices of the European Mechanics Society (EUROMECH www.euromech.org).

The Advanced Computational Materials Engineering Laboratory (ACME Lab), in the Department of Mechanical Engineering at The University of Alabama is seeking qualified candidates for an open PhD position. This position is open to US citizens only.

Ondřej Rokoš, Vlado Menkovski, and Marc Geers (all from the Eindhoven University of Technology), together with Martin Doškář (Czech Technical University in Prague), are searching for a motivated Ph.D.

The Nanoscale Mechanics and Materials Laboratory (NMML) at the University of California, Irvine is accepting applications for an open postdoctoral scholar position.  The research will focus on atomistic modeling of linear complexions, or nanoscale phases stabilized by the presence of dislocations.  Specific goals include the study of linear complexion nucleation and structure, as well as the impact of these complexions on subsequent dislocation plasticity.  An individual with a strong background in computational materials science is sought, and a Ph.D.

Analysis of deformation mechanisms and structure-property relationships within metallic glasses.

In this paper, we discuss two problems concerning scattering and localisation of flexural waves in structured elastic plates. Firstly, we compare the scattering amplitudes of waves in a thin plate, generated by a point source, due to a single mass and to a large number of smaller masses, having the same equivalent mass and located around a circle. We show that in the second case, the scattering can be reduced, in particular in the medium- and high-frequency regimes.
