Assessments of bolted joints can be performed for a number of reasons. Before starting any FE modelling of bolted joints it is important that the analyst considers the purpose of the analysis and plans it. A summary of typical aspects which should be considered during the planning will be covered.

The structural and thermal behaviour of bolted joints can be affected by a range of factors, including pretension, relaxation, friction and gasket properties. A discussion of factors which may be relevant will be given.
A number of FE modelling techniques can be used to analyse bolted joints. These will be described, along with their benefits and limitations.
