MATERIAL PROPERTIES FOR REACTOR PRESSURE-VESSELS AND CONTAINMENT SHELLS UNDER DYNAMIC LOADING

The effects of high strain rate, dynamic biaxial loading and deformati on mode (tension, shear) on the mechanical properties of AISI 316 aust enitic stainless steel in as-received and pre-damaged (creep, LCF) con ditions are reported. This research was conducted to assess the perfor mances of the containment shell of fast breeder reactors. The results of this research have been utilized to prepare similar investigations for SA 537 Class 1 ferritic steel used for the containment shell of LW R. The first results of these investigations are reported. A programme to study the mechanical properties of plain concrete with real size a ggregate at high strain rate is described.
