| Abstract: | Boss structure is in common use to reinforce the hole.ANSYS is used to creat the finite element model of boss structure,then compared the fracture characteristic of the single-side boss structure and the double-side boss structure.The result is got will provide reference and guidance for the design of boss structure with the hole. |
| |
| Keywords: | boss structure with the hole fracture mechanics stress intensity factor damage tolerance |
