A study concerning material fracture toughness and some small punch test data for low alloy steels

摘要: Abstract The present study has demonstrated the existence of a significant relationship between small punch energy and biaxial strain at point failure. Furthermore, using published trends relating fracture material toughness, relationships concerning toughness values were generated. It was shown that predictions from certain such exhibited good commonality with real data. one which related to non-metallic inclusion distribution promising while other models based upon microstructural details scale roughness factors less successful. This must be considered provisional in nature since it represents first attempt data as such, contains few assumptions are somewhat tentative.
