Modelling of an asymmetrical preloaded bolted ange joint, loaded with a normal external force is presented. The physical model of the joint is designed as a pair of elements (which are a flexible flange element and a rigid support) clamped using simplified models of bolts. Between the joined elements the Winkler model of a contact layer is introduced. The impact of nonlinearity of the contact layer on operational forces in the bolts is analysed. Conclusions of major importance to modelling of preloaded bolted flange joints are put up.
