Hello!
I did just a trial calculation in Hilti Profis Anchor software.
I used only one anchor HST-M10 and loaded it with both max. resistance tensile NRd = 6 kN and shear VRd = 18.8 kN load (values are for cracked concrete).
See screenshot.
Utilization is:
Tension: 100%
Shear: 100%
-> both...
Can somebody explain me what the numbers marked red in the attached picture mean. And give me some example.
I´m not sure if I get it right. First, for solver parameters. There are 100 steps with 0,02 time increment. So those two numbers multiplied give us 2. Does 2 represent the total applied...
Hi, Blas!
Thanks for replying. The contact has been set exactly the same way as in the previous simple model that we discussed before.
I will attach the new model here.

Hi!
Can somebody, please, explain why the top bolt is moving out of the hole? That´s happening to two other bolts on the other side of the part. The simulation runs without errors (but stresses in all parts are negligible so I guess there´s some problem in analysis). Bolts have following...
UPDATE:
I just found in Advanced Nonlinear Theory and Modeling Guide that:
´´Both small and large displacement formulations can be used for
the bolts beam elements. Any cross-section available for the beam
element can be used, but only the isotropic elastic material model
can be used.´´
I...
Hi!
I changed my model´s property and material.
Analysis still won´t run if I use Nonlinear Elasto-Plastic material.
Attached is the model file. Bolt shank material is ID 2 (Nonlinear Elasto-Plastic) and property is ID 4 (Nastran ROD, PBEAML/PBARL).
The results can be obtained from linear...
Thanks a lot, BlasMolero.
I ve never used this NASTRAN cross section before. I guess that s what I was missing. I think it should work now. I m on holidays now, but will try that next week and let you know if it works.

Yes, I found that in the Advanced Nonlinear manual, but how to set that up? I made a BEAM element property with CIRCULAR BAR cross-section and it doesn't work. And how to set up the bilinear plastic material?
Thanks, I know that, but it should be possible to use non-linear plastic material for BEAM (not BAR - maybe in this model it's BAR element, but it doens+t work with BEAM either) element in Advanced Nonlinear Analysis. I have to do that because I'm modeling 10.9 bolt material. This here is just a...
thanks for reply, but that's not an issue. i am aware of everything. the bolt shank will be just axially loaded and i want to avoid contact between shank and the hole in plates.
i just need to run analysis which can handle both contact and preloaded bolt.
Hi!
I´m trying to model a preloaded bolt which connects two metal plates. The plates and bolt head/nut are 3d SOLID and bolt shank is a preloaded BAR/BEAM element which is conectid with spider curves to bolt head/nut.
Since there´s a contact between elements I have to use Advanced Nonlinear...
