Question:
The fatigue data for a brass alloy are given as follows:
Stress Amplitude (MPa) ______________ Cycles to Failure
170 ..................................................... 3.7 × 104
148 ..................................................... 1.0 × 105
130 ..................................................... 3.0 × 105
114 ..................................................... 1.0 × 106
92 ....................................................... 1.0 × 107
80 ....................................................... 1.0 × 108
74 ....................................................... 1.0 × 109
(a) Make an S-N plot (stress amplitude versus logarithm of cycles to failure) using these data.
(b) Determine the fatigue strength at 4 × 106 cycles.
(c) Determine the fatigue life for 120 MPa?
