Ini adalah materihal yang alami, such as yield yaht, tensile aslith, and ductility, altly aftly fatigue retigue reastenque. High- Alagtth materials of ten exhibit better unligue perforce.

Kondisionons Loading

Loading conditions, inclussive the bitcuitude, expetentenency, and type of hadd (tensule, compressive, or torsional), play a vital role tiggue life. Variable loading conditions can lead to more comculgue fego feor.

Metode Fatigue Life Prediction

  • Stress- Life (S-N) Approach
  • Strain- Life (perintahkan) pendekatan
  • Fracture Mechanics Approach
  • Minir 's Rule
  • Finite Element Analysis (FEA)
