    Residual Stresses

    Hi,


    Is there a way to incorporate residual stresses in FEBio simulations? Perhaps by introducing initial element data?

    Thanks,


    David.

    Hi David,

    Residual stresses can be introduced using "multigeneration" materials, see the related page in the User's Manual.

    PreView does not yet provide a method for creating this type of material. The easiest way is to create a "solid mixture" material, then modify the .feb file manually to enter the <Generations> in the <Globals> section, rename the "solid mixture" to "multigeneration", and specify a gen id for each <solid>.

    You can check out the sample files mg01.feb and mg02.feb in the Verify folder.

    Best,

    Gerard
