In the deep-sea environment, pipelines are prone to buckling instability under the coupling effect of hydrostatic pressure and corrosion defects. This instability phenomenon is affected by the pipe dimensions, material parameters and corrosion defects. Based on the shell buckling theory, a semi-anal...
