Abstract
Dynamic tension and Taylor impact experiments were performed to study the high-rate inhomogeneous deformations in polymers under a range of conditions. The mechanics of deformation were examined utilizing finite element simulations together with a physically based constitutive model of large-strain high-rate deformation behaviour of polymers. The comparison of the numerical predictions with the high-speed photographic data and final deformed shapes demonstrates the effectiveness of the constitutive model in predicting the progression of complex inhomogeneous deformation events during impact loading scenarios.

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.
