    • Abstract
  • Adopting three-point bend SE(B) and compact tensile C(T) specimen,through crack-tip opening displacement CTOD fracture toughness test at-20℃ and fatigue crack propagation rate da/dN test,resistance to crack initiation and propagation of S355N and S355N-Z25 structural steel plates were studied.The results manifested that S355N steel is stronger in resistance to crack initiation and prophase growth than S355N-Z25 steel,but is weaker to crack anaphase propagating.When stress strength factor ΔK is less than 34.3MPa·√m,S355N steel has less fatigue resistance than S355N-Z25 steel.When ΔK equals 34.3MPa·√m,both have the same fatigue resistance.When ΔK is more than 34.3MPa·√m,the former has stronger fatigue resistance than the latter.These information may provide reference for the steels as used in safety-assessing of engineering structure.
