Abstract��Cyclic stress loading analysis was conducted on TRIP steel and DP steel by using ANSYS12.0 finite element software. Fatigue service life coefficient analog computation was conducted on TRIP steel and DP steel based on Miner fatigue accumulated rule. Results showed that under the action of 0-560 MPa cyclic loading stress�� the fatigue service life coefficient of TRIP steel plate was 0.002 6 while that of DP steel plate was 0.26. If fatigue service life coefficient is closer to 1�� then the cumulative damage degree under the stress amplitude is higher and its fatigue performance is weaker. Because the fatigue service life coefficient of DP steel plate is far more than that of TRIP steel plate�� i.e. the cumulative damage of TRIP steel plate is far less than that of DP steel plate�� TRIP steel plate has higher fatigue performance.
