Some considerations on instability of combined loaded thin-walled tubes with a crack

M. Shariati, A. Akbarpour

­­­­Ferdowsi University of Mashhad, Mashhad, Iran
Abstract: Instability of a thin-walled stainless steel tube with a crack-shaped defect under combined loading is studied in this paper. Furthermore, the effects of the tube length, crack orientation, and crack length on the buckling behavior of tubes are investigated. The behavior of tubes subjected to combined is analyzed by using the finite element method (by Abaqus software). For cracked tubes with a fixed thickness, the buckling load decreases as the tube length and the ratio of the tube length to its diameter increase. Moreover, the buckling load of cracked tubes under combined loading also decreased with increasing crack length.
Keywords: crack, finite element model, instability, thin-walled tubes, combined loading.
