Abstract Using finite element method （FEM）， the loading process of four-point bending fatigue test of austenite steel was simulated， the stress distribution and fatigue life of the specimens were analyzed， and the reasonable size range of the samples with uniform stress distribution was determined. Four-point bending fatigue test of a Cr-Mn austenitic steel was carried out， and the differences between the finite element simulation and the experimental results were compared and analyzed. The stress distributions between the two loading rollers are different with different sample sizes. The maximum stress appears near the inner side of the loading rollers （0.4-0.5 mm from it） with[t/h>1.4；]With[t/h＝1.2-1.4，] the stress distribution between the two loading rollers is uniform， and the error between the maximum simulated stress and the load stress （theoretical value） is within 5%；with[t/h<1.2，]the maximum stress occurs in the middle of two loading rollers， and it is close to the load stress as[t/h＝0.7-0.8.]The fatigue cracks occur in the middle of the two roller after fatigue tests and no fatigue crack appears at the outside of loading rollers， which is consistent with the simulation results. The simulated fatigue limit is 498 MPa with about 4.0×106 cycles， and the fatigue test limit is 505 MPa with about 3.6×106 cycles. The calculated value is slightly less than the experimental value which shows that the fatigue life can be predicted using the finite element method.
