000012634 520__ $$2eng$$aThe load bearing behaviour of a preloaded bolted assembly is mainly influenced by the lubricated mating threads of the bolt and the nut. Especially when parts of a bolted assembly shall be reused and consist of different materials, an understanding of the load distribution in the mating threads and the bolt is of great importance. Typical applications for this kind of connections are blind hole connections in transition joints and bridge bearings where high strength bolts are screwed in cut threads made of mild steel. For the numerical simulation of the preloading procedure a full parametrized 3D finite element model of a bolted assembly was built up and calibrated to experimental results achieved from tightening tests using a tightening torque testing machine. In the finite element model, the nonlinear material behaviour as well as the realistic coefficients of friction can be taken into account. To assess the reusability of different parts of the bolted assemblies, plastic deformations can be quantified and evaluated.
