 Summary:
 Contact finite element analysis (FEA) is a powerful tool for analysing and dimensioning of various connections. It is especially applicable in steel structures connected by bolts, where a contact between the bolt shaft and the bolt hole is a way of shear force transfer. Classic analysis of such connection simplifies the problem, thus reducing the complexity of the calculation. On the other hand, contact FEA gives much more detail of the connection behaviour. A simple example of thimbles connected by single bolt demonstrates advantages of the contact FEA solution performed by ANSYS software, but also poses questions regarding codification of the results of such calculation. Controlled and limited plasticization is one of the crucial problems which needs valid interpretation.
