| Abstract | ||
| Fatigue analysis helps in predicting life of the component and seeks improvements of the whole process in design phase. Efforts are continually made to combat the fatigue phenomenon, yet certain mechanical components are still failing due to fatigue. The present work proposes a laminated design of beams, which undergo fatigue. The well-known Paris-Erdogan formula was used to theoretically predict fatigue life of the proposed design. The design was shown to enhance fatigue properties through laminating the cross section of the component; Barriers in front of a propagating crack is deliberately included by lamination. Spectacular levels of improvement in the fatigue life of up to 102% were achieved by replacing the monolithic type by only seven laminates. The present analysis was proved efficient in verifying the anticipated improvement acquired by the proposed design of laminated beams. | ||
