Hello all,
This is my first post on these forums, so I would like to say helloto everyone :-)
So far at our company we have done FEA (Linear Static) ofstructural assemblies involving bolts & nuts tightened to aspecified preload torque - which is converted into tensile contactforces using the thread equation F=T/(0.2*D) and applied at thecontact areas between each bolt with the contacting plate &each nut with the contacting plate.
However, I recently read in an internet article that the best wayto simulate bolt preload in FEA is to perform a Non-Linear Analysiswhich takes into account thermal stresses induced in the membersdue to friction/tightening. I am interested in learning more aboutthis, so could someone please tell me what it exactly means &which books or internet articles would you recommend us to studyabout non-linear themal analysis in detail?SolidworksSimulation
