    Boltpreload and displacement in contact

    The sol101 has two different types of connection. Linear connection and glued. I used the first one. The second one has no traction on the contact region. But you bring me on another idea. To get the preload of 10KN we have to deform our beam about 0,012mm (dl=F*l/(EA)). My deformation in...

    Boltpreload and displacement in contact

    Hello all, Im working on a way to simulate a bolt contact with the sol101. For sol 601 I don’t have the license. In most cases its working for my problems well. But found a problem if I use friction to stop movement. I can see a small displacement in my connection. To check this I build this...

    Hello in the last version of NX Nastran they added a new feature for bold preload. Currently I use to calculate bold connections beams with a spider element. Why not using this new one. (excepting calculation time) So doing a short example...because in internet i didnt found anything about it...

    Moment on Solid

    Hello thank you for the answer, I tried it in both ways. First my analytic solution for the problem. My sandbox element is a rectangle profile with 100 mm x 100 mm and a length of 1000 mm. After I added a Torque of 1knm at the center of the surface and direction of x-aches. (Point and...
