Abstract
The purpose of the present investigation is to obtain easily the stress behavior of bolt on bolted joint which is received to external force. The bolted joint is confined to receive symmetric force with respect to bolt axis. At first the modeling method for bolted joint has been shown by being assembled to the structure constructed by spring and beam elements. The model has been analyzed by finite element method. And then the way described above has been applied on the through bolted joint and stud bolted joint which has nonsymmetrical compression area about contact surface of clamped plates. Also some experiments are simultaneously carried out under the same condition of the above model. The obtained results are as follows : (1) On the relation between the axial tension of bolt and external force acting on the bolted joint the calculated results are consistent with the experimental ones. (2) When initial clamping force become large, the external force for complete separation of contact surface need to increase.
