Finite Element Simulation and Experiment of Mechanical Expanding for Longitudinal Welded Pipe

Abstract

A two-dimensional finite element simulation model of longitudinal welded pipe is established by the nonlinear finite element software ABAQUS. Testing enlargement mould is used for the expanding experiments for the welded pipe under the laboratory condition. The expanding force, ovality and the shape are simulated and measured. Comparing the experimental and the simulated results, the values are fitted well.
