Mean stress with miner's rule in fatigue analysis

Click For Summary
SUMMARY

The discussion focuses on the integration of mean stress considerations, specifically using the Goodman equation, with von Mises stress criteria in the context of fatigue analysis employing Miner's rule. The primary inquiry is about converting loads with non-zero mean offsets into fully-reversed equivalents to accurately assess fatigue life under variable loading conditions. This approach is essential for engineers dealing with fluctuating loads in structural and mechanical components.

PREREQUISITES
  • Understanding of Miner's rule for cumulative fatigue damage
  • Familiarity with the Goodman equation for mean stress correction
  • Knowledge of von Mises stress criteria in material failure analysis
  • Experience with variable loading scenarios in fatigue analysis
NEXT STEPS
  • Research the application of the Goodman equation in fatigue analysis
  • Explore methods for converting mean stress to fully-reversed loading conditions
  • Study the implications of von Mises stress in variable loading scenarios
  • Investigate advanced fatigue analysis techniques for complex loading patterns
USEFUL FOR

Mechanical engineers, structural analysts, and fatigue specialists involved in the design and assessment of components subjected to variable loading conditions.

Hi

I was wondering how you would account for mean stress (such as using with goodman equation) using von mises with miners rule due to variable loading

Thank you

Are you asking how to convert a load with non-zero mean offset to a fully-reversed equivalent?
