... locus will cause failure in fewer than Af cycles. Any alternating stress-mean stress combination that lies within the locus will result in more man N cycles without failure. Combinations ... Combinations that just touch the locus produce failure in exactly N cycles. The modified Goodman relationship shown in Fig. 18.38 considers fatigue failure exclusively....

... fatigue failure is a combination failure mode in which all of the conditions for both creep failure and fatigue exist simultaneously, each process influencing the other to produce failure. ... falling within the curve, no failure is predicted. For points falling on or outside the curve, failure is predicted to occur. 18.1 CRITERIA OF FAILURE Any chan...

... synergistically with another failure mode, such as wear or fatigue, to produce the even more serious combined failure modes, such as corrosion wear or corrosion fatigue. Failure by corrosion ... corrosion may combine their influence with other failure modes to produce premature failures. Of particular concern are interactions that lead to failure by corros...
