In the actual engineering structure,such as aerospace,ship and civil engineering,it is often necessary to fix up an appropriate number of cutouts based on experience for structural maintenance,weight reduction or performance optimization.On one hand stress concentration occurs around the cutouts and the static strength of the component is reduced;on the other hand,the quality and stiffness distribution of the structure will change for the existing cutouts,which have a great influence on the mechanical properties such as natural frequency,structural load-bearing performance of the structure.Therefore,analysis of the mechanical properties of the structure with cutouts has been a hot issue in the research,which is of great significance in the engineering structure design.
