Abstract
Various types of specimens machined from fuel claddings are considered and methods of their tests are analyzed. The disadvantages and advantages of existing methods are considered from point of view of obtaining adequate mechanical properties for highly embrittled materials. On the basis of the performed analysis and calculations the new ring specimen is proposed and the method of its testing and processing of experimental data is developed which takes into account the friction between the loading device and speci men and allows determining the mechanical properties and obtaining the true stress-strain curve for fuel clad ding materials.
