Hello everyone,<\/p>\n
I am doing a simple model of single bolted joint which is clamping 2 plates together.<\/p>\n
The problem is that after applying the pretension in the first step, locking it in the subsequent step and finally apply a an axial force on the plates results get physically incoherent.<\/p>\n
The workload I extract from the simulation with the bolt tool is either below pretension value or exactly the value of the applied external load.<\/p>\n
I have hand calculated the fraction of external load carried by the bolt and it should be about 24 % which is very far from what I get.<\/p>\n
I am using an M10 bolt made up in Standard Steel Non-linear and Aluminium Alloy Non-linear for plates, I activated NLGEOM in analysis settings went through tutorials which describe the same geometry as mine and still it doesn’t work.<\/p>\n
I have used the same principle than in this video: Mechanics of Bolted Connections — Lesson 2, Part 3 – YouTube<\/a><\/strong><\/p>\n I have changed boundary conditions many time, geometry and so on, still I have the same problem with the workload of the bolt which doesn’t seem to care about the external load I apply, nothing from it is transferred into the bolt.<\/p>\n I’d be glad to here from you people about that issue, thanks for considering my request.<\/p>\n Arthur <\/p>\n
