Abstract

Based on large-scale experimental tests performed on cruciform specimens made of French type RPV steel, the warm prestressing (WPS) effect for LCF (load–cool–fracture) and LCTF (load–cool–transient–fracture) load cycles is studied by finite element simulation. The modified Beremin model is used to determine the fracture probability of the specimens.
