Mathematical modeling of residual stresses in spiral welded pipe
Journal Title: Вісник Тернопільського національного технічного університету - Year 2018, Vol 90, Issue 2
Abstract
Using the Kirchhoff thin shell theory with initial stresses the mathematical model for determination of residual welding stresses in pipes with spiral weld joint was built. The values of welding stresses acting on face surface of pipe for varying helix angle of spiral weld joint in pipeline was calculated.
