    Residual stress caused by yielding - bending

    What kind of heat treatment should be used to minimise the residual stress taking into account that the mechanical properties of steel shall not be affected by the treatment ? Thanks for your help.

    Residual stress caused by yielding - bending

    A rectangular bar 1/8" thick x 2.5" wide x 30" long made of Hardox 450 steel (Fy = 170 ksi) is bent 180 degrees at the center of the bar (out of plane bending) with an outside radius of 1.25". What is the residual stress at the bent section ? Is this a simple calculation or requires FEA ?
