Ductile fracture of BS4360-50D steel and the relationship of J-integral and COD

Ductile fracture of BS4360-50D steel and the relationship of J-integral and COD

The relationship of two parameters characterizing fracture toughness, J-integral and COD, is analysed and applied in the investigation of a low-alloy mild steel. It is shown that the value of the parameter M in the formula J = Mσ y δ decreases with temperature, but is not influenced by the ratio a/W...

Beschreibung
Zusammenfassung:The relationship of two parameters characterizing fracture toughness, J-integral and COD, is analysed and applied in the investigation of a low-alloy mild steel. It is shown that the value of the parameter M in the formula J = Mσ y δ decreases with temperature, but is not influenced by the ratio a/W. Suitable equations to estimate the value of M are presented.
