ABSTRACT
The modal and stress distribution of the RBE2 element and CFAST element can be obtained through the MSC NASTRAN to simulate bolt connection. After comparing the modal results of the two kinds of element, we conclude that the simulations are slightly different between RBE2 and CFAST and both of them can be used in the simulation of bolt connection. However, their stress results are not consistent. The stress result of the CFAST element is more in line with the actual situation, so it is more suitable for the simulation of stress. By comparing their advantages and disadvantages in terms of modeling and the results of modal and stress, the CFAST element is more suitable for the simulation of bolt connection.
