摘要：

The stress intensity factors (SIFs)-K are investigated for surface cracks in the thread ground of 30CrMnSiA bolts used in the aircraft structure on the basis of the simulated experiments. According to the SIF research achievements obtained of the thread fastener, the equations for the SIF-K are developed by means of analogy for surface cracks in the thread ground of the bolts under the condition of well-considered thread elements. Experiments are conducted to study the influence of the thread on fracture mechanics features of the structure member. The comparison of SIFs between the analytical results and experimental results is made. It is shown that a good agreement is achieved between the experimental results and analytical results evaluated by using the SIFs' equation derived by the author.
