Abstract

The mechanical behaviors of composite bolted joints which are typical connection units of aircraft structures might change due to the application of liquid shim or laminated shim with different thickness. In this paper, the bearing capacity of composite bolted joints with different shim are studied numerically by three-dimensional nonlinear finite element (FE) method, and the extended Chang-Lessard failure criteria is incorporated into FE model to predict the progressive damage of composite bolted joints. Finally, the numerical results are verified experimentally. It is concluded that the stiffness and strength of the composite bolted joints decrease with an increasing shim thickness, and the composite bolted joints with laminated shim get better bearing capacity than the liquid shim series with same geometry size.
