Shock waves and the heterogeneity of materials

Abstract
In a shock front, the evolution of thermomechanical state variables, although being continuous, occurs with a characteristic length smaller than the size of an elementary relevant volume (E.R.V.) of the material. So, the problem should be solved at this mesoscopic scale; nonetheless, we show that it is possible to derive jump relations on mean values at the macroscopic scale so long as the local problem satisfies some properties of “homogeneisability”.

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.
  • If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
  • You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
  • You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
