fracture

During charging or discharging of a lithium-ion battery, lithium is extracted from one electrode and inserted into the other.  This extraction-insertion reaction causes the electrodes to deform.  An electrode is often composed of small active particles in a matrix.  If the battery is charged at a rate faster than lithium can homogenize in an active particle by diffusion, the inhomogeneous distribution of lithium results in stresses that may cause the particle to fracture.  The distributions of lithium and stress in a LiCoO₂ particle are calculated.  The e

Dear iMechanica commmunity,

we are looking for 3 PhD students at Oxford, starting from the 1st of October 2010 or as soon as possible thereafter. The closing date for the application is the 26th of July. The 3 students are required for two different research projects, namely:

1) Underwater blast on composite structures - open only to EU nationals; 2 PhD students are required. The studentships are advertised here

A PhD position is available at Centre Henri Tudor (Luxembourg) and Cardiff University (UK) on the simulation of crack propagation with adaptive extended finite element methods.

Candidates from any country are eligible. 

Please contact me for details.
