摘要: Abstract Creep crack propagation rates have been measured in Type 316 steel at 625°C and correlated terms of linear nonlinear elastic fracture mechanics parameters. Two differing specimen geometries from each two different casts used it appears that growth predictions based on a net section stress correlation are preferred to those intensity factor or the creep energy rate line integral C ∗. More importantly an effect geometrical constraint has observed, with decreasing increasing constraint.
