Nonlinear Finite Element Analysis - Ansys analysis (bolted joint)

[@mwave3388]

Thanks very useful. How do you define what kind of simulation constraint or support you should use for different contacts?

[@nguyenthanhtung9187]

Thank you very much !

[@ayomasukaja]

will be nice to get overview solid bolted joint vs shell bolted joint in result and speed. Especially when we have a lot of bolts.

Ola! Neste momento preciso de simular no ansys uma ligação coluna placa de base fundação. Ja modelei e parametrizei no ansys, no entanto, está muito complicado correr a simulação. Eu pretendo aplicar um esforço axial, de maneira a verificar qual o valor máximo que a ligação aguenta sem ceder, no entanto, mesmo aplicando uma carga de apenas 1 N, o ansys nao me resolve e aparecem erros nos elementos altamente distorcidos :(:( Agradecia imenso a sua ajuda!

CAN u advice me any source that i can get data about 253MA outokumpu's nonlinear isotropic hardening and temperature dependent values ?

very helpful thank you

Thank you for your comment!

Sir welding changes material property at welded parts .so can you make videos on the same design with using welding

[@femhelper3963]

Thank you for your comment. I already have one video about a welded connection using nonlinear materials. Probably, in the future, I will look into weldings again :)

hello dear. Where can I watch your big tutorial about the meshing and bolt pretension as you mentioned half year ago bro. Thanks

[@femhelper3963]

Hello sir. Well, things got busy as usual. I've not forgotten about it. It will be on the air soon.

Hi! Is it possible to make a simulation like this one directly in Inventor?

[@femhelper3963]

Hello Pietro. Thanks for your comment. Actually, it is! However, the results won't be as accurate as in Ansys, especially if you're leading with non linear materials

[@irdotcomid741]

HELLO, SIR. IT WAS GOOD EXPLANATION. BUT, PLEASE LET ME KNOW, HOW TO MAKE THE BOLT ON ANSYS. AND WHAT CONTACT YOU USE TO IT?

[@schoolie78]

what tangent modulus did you use? Also, can you go over the meshing and bolt pretension?

[@femhelper3963]

Thank you for your comment. Well, the material used in this specific analysis is the standard non-linear steel available in Ansys. The tangent modulus of this material is already specified in the material properties. You can check that quickly by clicking on the "Engineering data" menu. Regarding the meshing and bolt-pretension, I'll be doing a video about that any time soon. However, do you have any doubt about the meshing and/or bolt pretension settings in this analysis?

@@femhelper3963 hi, thanks. I was just wanting you to drill down into those two subjects a little bit so I can see how to do it.
