Drop-Weight Tear Tests on Line Pipe . The need for a determination of the fracture toughness of line pipe was considered in 1964 and at the midyear meeting in 1965. Certain ground rules were submitted at the 1965 meeting for the development of a specification on . The methods of conducting this test and evaluating the results are described . Abstract. The drop-weight tear test (DWTT) has been widely used to evaluate the resistance of linepipe steels against brittle crack propagation, and the shear area fraction SA% in the DWTT has been adopted in the requirement for the linepipe steels. However, recent studies have pointed out the issue of ambiguity in evaluation of the DWTT when a ductile crack .DOI: 10.1115/OMAE2002-28183 Corpus ID: 135665297; Evaluation for Abnormal Fracture Appearance in Drop Weight Tear Test With High Toughness Linepipe @inproceedings{Muaoka2002EvaluationFA, title={Evaluation for Abnormal Fracture Appearance in Drop Weight Tear Test With High Toughness Linepipe}, author={Ryuji Muaoka and .
