| Abstract: | In this paper,the vibration properties of 1Cr18Ni9Ti stainless steel plate used in hydraulic pipes are studied at cantilevered restraint and the first grade natural frequency.The S-N curve of 1Cr18Ni9Ti stainless steel plate has been got,the fatigue limit is 218 MPa.The crack initiates at the surface of specimen,the beach marks are found on the fracture surfaces which shows the fracture is a typical fatigue failure. |
