homogenisation

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.

Micromechanics-based Nonlocal Continuum Models organised by Lorenzo Bardella (University of Brescia) and Samuel Forest (Mines ParisTech CNRS) http://www.esmc2018.org/drupal8/node/96  Submission deadline: November 15th, 2017  Nowadays, problems involving more physics and more length and time scales have become very relevant in engineering applications. Theoretical frameworks limited to conventional continua are often inadequate to model such problems.

Applications are sought for one Post-Doctoral Researcher at University of California, San Diego (USA) and one Post-Doctoral Researcher at Cardiff University (UK) and two PhDs (Cardiff) to join a very active cross-continental M2DO research lab. The primary research focus is to develop topology optimization for multiscale and multiphysics problems optimizing materials and structures. The research members are required to travel between US and UK regardless of their bases.  

A recently published paper  "Evaluating the macroscopic yield behaviour of trabecular bone using a nonlinear homogenisation approach" links the micromechanics of bone to its macroscopic behaviour. The paper may be of interest to colleagues on this forum. The abstract is provided below.
