STUDY ON BRITTLE FRACTURE INITIATION IN STEEL STRUCTURES- 3RD REPORT

In general, brittle fracture of steel structure is preceded by the formation of a plastically deformed region ahead of a crack which in most cases is too large to be neglected in size compared with the crack length. A recent trend shows that the crack opening displacement (COD) theory is a powerful approach to fracture mechanics, especially for cases having a large scale yielding ahead of a crack. Authors have been investigating the application of the COD theory toward the analysis of brittle fracture initiation phenomena in relatively complex steel structures, and have found that the theory agrees with the analysis of brittle fractures of large structures. This paper deals mainly with the displacement behaviour of loaded members having cracks. Experimental data for COD using deep notch type specimens supports the theoretically calculated values. Using these results, the validity of applying the laboratory test results to the brittle fracture initiation in large steel structures is discussed.
