CECAM Workshop "Chemical and structural transformations in materials under mechanical load"

Submitted by pastewka on

We are pleased to announce a 4-day CECAM/Psi-k Workshop on

"Chemical and structural transformations in materials under mechanical load",

 that will take place at the EPFL campus in Lausanne from Tuesday 1st September to Friday 4th September 2015.

The focus of the workshop will be on materials’ structural and chemical transformations that are caused by external loads and in turn determine the materials macroscopic mechanical response. Particular attention will be devoted to the following thematic areas:

Fracture strength of micro- and nano-scale silicon components

Submitted by Frank W. DelRio on

Silicon devices are ubiquitous in many micro- and nano-scale technological applications, most notably microelectronics and microelectromechanical systems (MEMS).  Despite their widespread usage, however, issues related to uncertain mechanical reliability remain a major factor inhibiting the further advancement of device commercialization.  In particular, reliability issues related to the fracture of MEMS components have become increasingly important given continued reductions in critical feature sizes coupled with recent escalations in both MEMS device actuation forces and harsh u

Temperature induced crack propagation in structured media

Submitted by Giorgio Carta on

This paper describes the propagation of an edge crack in a semi-infi nite triangular lattice, consisting of identical point masses connected by thermoelastic links. A change of temperature, represented by a time-periodic series of high-gradient temperature pulses, is applied at the boundary of the lattice. In order to make the initial crack advance in the lattice a failure criterion is imposed, whereby the links break as soon as they attain a prescribed elongation.

A DOCTORAL STUDENT POSITION IN FRACTURE OF SEA ICE

Submitted by Jukka Tuhkuri on

Aalto University School of Engineering in Finland has an open position for a doctoral student in the Arctic Marine and Ice Technology research group at the Department of Applied Mechanics. Our research group studies the behavior of ships and structures in ice, ice mechanics and also assesses the impact of sea ice on the safety of maritime transportation. An important part of our research is experimental work. For that we have excellent possibilities as we operate the Aalto Ice Tank, a 40 m × 40 m ice model basin.
