摘要：
Finite element modelling procedures were developed to examine the effect of pipe diameter, ovality, wall thickness, imperfection formulations, joint-to-joint material strength variation and radial weld offset on the pipe mechanical response through numerical simulation of the reeling process. This study examines the pipe deformation, stress concentration, and strain discontinuity developed during simulation of the pipe reeling process. The key parameters influencing the pipe mechanical response are identified and recommendations on future work provided.
