I am attempting to run a study on 2 parts clamped together using
special fastenings, and i'm interested in ways of applying an axial
preload to the fastenings.
I've tried using a drop in temperature to give the preload which I
believe is a technique used in older FEA systems. When I run the
study using standard connectors the reation force on the clamped
part is roughly the sum of the pre-load. 4x M16 bolts with a axial
preload of 46.6KN is this what would be expected? But I get
different results from the special fixings?
