Abstract
The numerical and experimental verification is performed of the proposed method for determination of standard mechanical properties and the true stress-strain curve for fuel cladding material by ring specimens testing and FEM modeling of their loading (see Part 1 of the article). The tests results of the proposed ring specimens are represented for EP823 steel (12Cr-Mo-W-Si-V-Nb-B) in the initial and irradiated states over a wide temperature range when using various lubricants and without lubrication. Based on the obtained results of these tests, the mechanical properties and true stress-strain curves are determined for EP823 steel.
