Abstract
Constitutive equation for the hereditary type media under high rates of loading with temperature effects is proposed. It is based on the original principle of temperature inclusion in hereditary integral equation. The curve $\varphi (\varepsilon )$ , which is the curve of instantaneous deformation, is considered at the same time as the curve of absolutely zero temperature. It is the equation of curve, which bounds the whole process of loading from above. The cases are considered when the history of temperature changing can be neglected and we can take f[ T(t), $T(\tau )] = T^{\gamma }(t)$ , where T – temperature in Kelvin degrees. The examples are given, which show an analogy between the processes with abrupt changing of loading rate and abrupt changing of temperature.

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.
