Abstract

In the past time, it was neglected that different types of the deformation have an important effect on the Load-Displacement (L-D) relationship in bolt slippage. In this paper, 3D finite element models with double bolt joints are established by the ANSYS finite element package and a series of bolt slippage tests are conducted. The large lateral deformation in the process of bolt slippage is put forward for the first time. Numerical and experimental results show that large lateral deformation makes the stiffness of bolt joint smaller.
