Abstract
The article presents the general characteristics of bolt-rivet joints. The main structural parameters of bolt-rivet rods affecting premature shank tearing are given. Stages of rod installation process into hole are described and critical moments of shank tearing are determined. A graph showing the variation of the rod retraction force depending on the thickness of the package is obtained, and basic parameters are determined for comparing two types of rods with different design, but the same purpose. Methods of determining shank tear- off forces, as well as stresses arising in the neck during retraction, using Femap software product are considered. Maximum stress values are calculated on the example of two types of rods and analysis of possible shank tear is carried out at available parameters of neck. In conclusion, it is noted that with the help of IT-technology it is possible to improve not only the design of joints, but also the technology of their implementation, by changing the design of fasteners.
