Dear colleagues,

I'm writing to bring to your notice the sad news that Prof. Jerry Ericksen of the University of Minnesota passed away on June 11th 2021.

Kaushik Dayal

There is an immediate opening of a postdoctoral researcher in the Mechanics of Soft Materials Lab (https://www.msm.seas.ucla.edu/) in the Department of Mechanical and Aerospace Engineering at the University of California, Los Angeles (UCLA). The research will be on experimental mechanics of soft materials, and fabrication of soft machines. The successful candidate should have a PhD degree with expertise in experimental polymer materials.

EML Webinar (Season 2) on 16 June 2021 will be given by Ju Li, MIT. Elastic Strain Engineering for Unprecedented Properties. Discussion Leaders: Sulin Zhang, The Pennsylvania State University

Time: 10 am Boston, 3 pm London, 10 pm Beijing on 16 June 2021

Zoom Link: https://ter.ps/EMLWebinarS2

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:
