...Igor Orynyak; Vladyslav Marchenko; Roman Mazuryk; Andrii Oryniak There are dozens of formulas in literature and standards for residual strength calculation of the pressurized ductile pipes with axial rectangular defect. Their accuracy is usually characterized by the so-called “model error” notion...

... transition model for circumferential cracks in pipes. The model can be used for pipe subjected to axial tension, global bending, and combined tension and bending. Since the model introduces the concept of a nonidealized TWC for describing SC to TWC transition, the existing K I and COD solutions...

... to diameter λ were analyzed by Eq. (25) , and the results are shown in Fig. 5 . The vertical axis represents the ratio of burst pressure of an eccentric pipe to that of a concentric pipe. One can clearly see from Fig. 5( a ) that the burst pressure ratio almost linearly decreases with the increase...
