Optimization of Pipe induction bending process by FEM

In this article, induction pipe bending process has been studied and by considering major affecting parameters, the forming conditions are optimized. First, a simple analytical solution is presented to predict forming conditions such as strains, stresses, pipe geometry, forces and moments. The results are also compared with FEM simulations obtained by ABAQUS software. According to analytical and computer simulation results, an appropriate reverse moment should be applied to the bending arm to keep the wall thinning and the ovality within an acceptable and required standard values. The results are also compared with available experimental data. The results of analytical and FEM simulations are very well in agreement with experimental observations.
