The induction bending process for large-diameter pipes is very popular technology. An important problem in the bending process is prediction and improvement of the bending quality. A thermo-elastic-plastic mechanical model is used to simulate induction bending of large-diameter pipes. The bending experiments of the API 5L X65 induction bend pipes were performed to clarify the deformation behavior of the pipes. The large deformation behaviors of these experiments were simulated by finite element method, using ADINA software. The results of the introduced simulation approach via analysis of the residual stress, strain, and displacement distribution in pipe; analysis of the plastic stress, strain, and displacement distribution in pipe; analysis of the temperature distribution; and analysis of the pipe shape modification - ovality modification.
