4) Eqn. 6. 45. Lm respectively? 2) for simplicity. 45, then 363 cycles are predicted. 45 respectively. 7. Worked Example using Energy Criterion A component is required to operate under mixed cycling according to the scheme in the first three columns of Table. 2. 15. 0 Jmm-3. Is crack initiation likely to occur in the component? 2: Data for Energy Calculation Given parameters Cycle type No. 325 ~a. 2. 15). 2. 0 Jmm-3 . Crack initiation is thus not likely to occur. This problem is returned to in Section 5.

P. Skelton If a dwell is imposed at peak tension for example, the extra energy expenditure, illustrated in Fig. 7 and is given by the expression [35]: ~. is ..... 16) Typical values of~. 3. Thus the extra energy expenditure during the dwell can account for a reduced number of cycles to failure (creep-fatigue interaction). 41 X 10-3 It must be noted that the energy values are a measure of heat which has been dissipated in the specimen or volume element of the component. The amount causing damage with each .
