This paper presents the method for predicting the maximum axial force
Fm of the bolt induced by tensile impact energy
E0 under the various conditions of the bolted joint with plastics bolt. First, the influence of clamped member and initial tightening force on the
Fm is investigated experimentally and prediction method that corrects the result of elementary test to a value corresponding to any given fastening condition is proposed. Second, the influence of different screw size and clamped length on the
Fm is considered for the purpose of generalizing this method. As the result, obtained conclusions are summarized as follows : (1) Influence of the spring constant of practical clamped member on the
Fm is negligible as compared with that of initial tightening force. (2) The proposed prediction method is applicable to the bolted joint with different screw size and clamped length by generalizing the
Fm by stress and the
E0 by impact energy per unit volume of the bolt.
