Composite Steel

Tensile experiments were conducted on composite–composite joints and composite–steel joints with countersunk bolts while three-dimensional finite element models using progressive damage method on composite were developed to simulate bearing failure of joints. Experimental results showed good repeatability and bearing damage showed obvious difference between the two kinds of joints. Solid elements were chosen to model all the parts and laminates were partitioned into actual number of plies in order to gain accurate stress distribution and damage profile in each ply. A 3D Hashin-type criteria and degradation rules were implemented using a user subroutine in ABAQUS. Numerical results had good agreement with experimental results considering clearance effects. Composite–steel joints showed better carrying capacity than composite–composite joints according to load–displacement curves and damage evolution processes. Delamination were more severe in composite–composite joints indicating that it is necessary to pay attention to designing composite laminates and structures under certain load condition.

Propagation Law

A three-dimensional explicit finite element method was presented to investigate the bearing failure of single- and double-shear composite bolted joints. To predict the various failure modes of composite laminates, three-dimensional solid elements accompanied by mixed-mode failure criteria considering nonlinear shear behavior were employed in the model. A linear damage propagation law based on the fracture energy and the characteristic length was adopted to alleviate the mesh dependency. In addition, reduced integration elements were used in the models of single- and double-shear joints to avoid the overstiffness. The simulated models were implemented in the Abaqus/Explicit solver with a user-defined material subroutine. The numerical analysis run successfully without any convergence issues. The predictions of mechanical behavior agreed well with the experimental results, with typical damages in the laminates including matrix crack and fiber failure. The effect of secondary bending in the single-shear bolted joint was also analyzed in the explicit modeling.

In this paper, an experimental study has been carried out to investigate the failure load and the failure mode of multi-pin joints of glass fibre reinforced composite laminates which have the stacking sequence of [0/±45/90/0]S subjected to a traction force. The laminates were manufactured by vacuum assisted resin infusion (VARI) and tested with a special fixture. The number of pins was set from 3 to 5, while there were two different arrang styles for each condition. The test results showed that the failure loads were directly affected by the number of pins and arrang styles.The ultimate failure loads increased with the number of pins.
