Abstract

A non linear finite element simulation is conducted which completely simulates the forming of the tube from flat virgin plate to its final shape. The predicted residual stresses and amount of cold forming in the tube sides and comers are then compared to actual experimental data from cold formed tubes where the initial material properties and the material properties after the cold forming process are known. This illustrates the usefulness of the non linear finite element method in predicting how the material properties change during cold forming and gives a useful insight in what the actual condition of the material is after cold forming.

The Effect of Cold Forming on Type 3CR12 Square Tubes

A non linear finite element simulation is conducted which completely simulates the forming of the tube from flat virgin plate to its final shape. The predicted residual stresses and amount of cold forming in the tube sides and comers are then compared to actual experimental data from cold formed tubes where the initial material properties and the material properties after the cold forming process are known. This illustrates the usefulness of the non linear finite element method in predicting how the material properties change during cold forming and gives a useful insight in what the actual condition of the material is after cold forming.
