The Basquin Law for an alloy tested at R=1 is Nfb(/2)=C. At a of 300MPa,Nf is 105 cycles, and at a of 200MPa,Nf is 107 cycles. (a) Determine the values of the constants b and C. (b) What is Nf for a stress range of 250MPa ? (c) If a specimen is cycled at 250MPa for 5105 cycles, how many additional cycles based upon the Palmgren-Miner Rule will the specimen be able to sustain at a stress range of 200MPa
