MICRO-MACRO DAMAGE SIMULATION OF LOW-ALLOY STEEL WELDS SUBJECT TO TYPE IV CREEP FAILURE

T.Igari

金属学报(英文版)

A simulation method for microscopic creep damage at grain boundaries in the finegrain heat-affected zone of low-alloy steel welds involving high energy piping was proposed on the basis of the combination of elastic-creep FEM (finite element method) analysis and random fracture resistance modeling of...
