Bolt Preload

The Connect Bolt Region command creates individual regions of a single element or multiple elements where you would like to apply a bolt preload. When analyzing a model with preloaded bolts, you may be interested in obtaining the stresses due to the preload condition alone or due to a combination of the bolt preload and additional loading conditions. This is all possible using Femap. Watch the video below to see this function.
