An elastic-plastic analysis of interference fit connection

Jiefeng Jiang, Yaxuan Bi

Abstract

Interference fit connection technique can effectively improve the fatigue life of aircraft structure. Considering the engineering practice, in this paper, the pin treated as an elastic deformed body is introduced in the analysis of interference fit connection. In the theoretical derivation, we obtain the contact stress between the hole and pin, the interference fit size of the elastic limit, and also the relationship between the plastic zone radius and interference fit size. At the same time, the finite element model is established, and the numerical simulation is conducted. By comparing theoretical and finite element results, the theoretical formulas are verified, which can be used furtherly in quick engineering calculation.
