| Abstract: | This paper conducted experiment research on plate type rubber bearing under allowable load systematically, analyzed the crack extension of rubber bearing according to the characteristics of stress concentration from the part that combined rubber with steel plate. The simple damage module is also build up and the development trend of bearing damage is predicted. |
| |
| Keywords: | rubber bearing damage model crack expanding stress concentration |
