Abstract: This study discusses the collapse criteria for thermally treated line pipe and their bending interaction against collapse based on a full-scale test under external pressure with and without bending loading. The critical ...

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 ...

Abstract: Pipelines are susceptible to significant longitudinal deformation in areas affected by ground movements, including slope movement, frost heave, thaw settlement, and/or erosion. The assessment of tensile strain capacity ...

Abstract: The drop weight tear test (DWTT) has been widely used to evaluate the resistance of linepipe steels against brittle fracture propagation. Although there is an ambiguity in the evaluation of DWTT results if inverse fracture ...
