Abstract
Non-linear deformations of a 12- and a 24-in. outside diameter butt-welded elbow subjected to in-plane bending are analyzed. The four-node shell element of the program ADINA/version 5 is used for geometric and material non-linear analyses. Verification of the element is indicated in comparisons with experimental data of the elbows. Efficiency and cost-effectiveness of the element are demonstrated.
