7) The AISI steel is subjected to cyclic load with a tensile mean stress of 200 MPa. Find the following: a) What is the life expected if the stress amplitude is 450 MPa? b) Estimate the , versus N, curve for the given , value Note: At zero mean stress, for AISI 4340 steel have a curve is 10: 1758 MPa and the slope (m) of the SN 7) The AISI steel is subjected to cyclic load with a tensile mean stress of 200 MPa.
