Modeling Residual stress in steel beams on ANSYS

  1. Apr 24, 2010 #1
    hello guys

    this is my first post here
    i am a PHD candidate, my research is to study the effect of several parameters on the capacity of overhanging beams with a C shape cross section, example UPN sections

    i have to take into consideration the effect of residual stress caused by the fabrication of the steel beam "UPN"
    i don't know how to model this stress, i am using shell element93 to model the flanges and the web of the beam.
    i tried to use the initial stress " inistate command " but i failed

    so please i need help in this issue

    thanks in advance
