Abstract：Under the given displacement load and based on the three-dimensional FE model of single-bolted composites laminate, factors influencing on the mechanical properties are analyzed such as the clearance between bolt and the hole and the hole shape when pretightening force isn’t taken into account and pretightening force when the different bolt material was selected by implementing the material failure criterion and property degradation rules into the user material program UMAT in ABAQUS software.
