    Tied Contact Algorithm

    Hey Guys,

    I'm currently using a tied contact option within FEBio for a model. The corresponding manuscript is in review and a reviewer asked for the specific details of the tied contact algorithm. I'm going to reference the theory manual. But just to be sure, the tied interface uses an augmented Lagrange method just like the sliding surface correct?

    Thanks,

    Brent

    Hi Brent,

    That is correct, the augmented Lagrangian method is used for tied contact. It might also be interesting to reference Tod Laursen's monograph, Computational Contact and Impact Mechanics. Most of the contact implementation in FEBio follows this book. Altought it doesn't take about tied contact, it does discuss in detail the augmented Lagrangian method for contact algorithms.

    Cheers,

      Hi Brent - would you please let us know about any published manuscripts, conference papers or peer-reviewed abstracts that make use of FEBio? We need to keep track of them as part of our commitment to our funding sources.

      We have been listing publications here, under the "publications" tab:



      Steve, Dave - could one of you post an "Announcement" on the forums, asking our users and developers to let us know about publications that make use of FEBio and/or PreView/Postview?

      Thanks,

      Jeff

        Hi Jeff,

        Is there a particular place on the forum that you would like me to send publication information to? Or should this be done through private email?

        Thanks,

        Brent

          Brent,

          There is a sticky item on the FEBio Users forum titled "Call for publications." Please post your publication information there.

          Thanks,
