modeling bolts

[CiccioViol]

Hello everyone,
I'm a new user, my name is francesco.
I hope you can help me with this modeling problem.

< I have a structure (composed by several parts) in which there are various bolted connections (I would like to check) so I need to use a "bolt model" from which can read the agent voltage and (magari) to which can apply a preload.
I've been documented a bit, and I've been oriented towards the technique that shapes the bolt stem as an element beam and the head of the bolt as a "network" of rigid elements, the preload would be a thermal load.
but the results I get are high.>>>

- you would know how to correctly assign the properties to the bolt, known: the stem diameter, head size, preload??- or would you have references or examples to which to refer??-I discovered the existence of a patran tool dedicated to bolted joints, some of you have ever used it??I thank you and hope that this debate will be of general interest.
Thank you.

Guys, tell me if I was unclear.

Hi, Ciccioviol.

I am doing the thesis on this topic, mechanical engineering master, I have a lot of material to show you, in literature there are many silumations that you can apply, you want me to send you the material for e-mail?

Hello, luca.
Thank you. You'd do me a big favor. :

My mail is [CUT]Thanks again.

I finally answered you to the mail, sorry for the delay.

We'll talk to you by email.

hi, much depends on the level of detail of the analysis, we hypothesize three scenarios:

- single bolt simulation
- bolted connection simulation between two parts (e.g. classic seal flange), dozens of bolts
- Large simulation of carpentry, hundreds or more bolts

for each scenario there are different techniques.
