Amachine component is to be designed for a life of 10° cycles. the working load will be cyclic and t100 mpa. a material has been chosen which follows basquin's law for high- cycle fatigue, i. e. ao(v; )-c, where a 0., ci 850mp2 and aois the cyclic stress range. the ultimate tensile strength for this material is 450 mpa it is anticipated that during manufacture and assembly, there will be some residual stress in the component. estimate the maximum mean stress allowable if the component is to retain a life of 100 cycles b) describe one technique for estimating the fatigue life of components which are subjected to a number of different loading regimes. c) describe briefly how you would deal with a stress concentration, such as a grooved shaft, when estimating the fatigue life of a component. d) during a routine inspection a crack is discovered in a component. outline how you would determine whether the component could be kept in service and for how long it could be kept in service
