疲労破壊靱性のBereminモデルによる検討

抄録

Experimental data on the fatigue fracture toughness test cited from two papers are shown to be well explained on the basis of the Beremin model. It is suggested that estimation for fracture probability of structures should be made by taking into account fatigue propagation path length, and that fatigue fracture toughness test might give a useful means to study the fracture probability in the low fracture toughness and low fracture probability region.
