Spec yield and ult strengths - true or engineering stress?

Click For Summary
SUMMARY

The yield and ultimate strengths specified in standards such as ASTM A36 are engineering stress values, not true stress values. This distinction is crucial for accurate material performance assessment in engineering applications. Understanding the difference between these two types of stress is essential for proper material selection and structural design.

PREREQUISITES
  • Understanding of engineering stress vs. true stress concepts
  • Familiarity with ASTM A36 specifications
  • Basic knowledge of material mechanics
  • Experience with structural design principles
NEXT STEPS
  • Research the differences between true stress and engineering stress in material science
  • Study the ASTM A36 specification in detail
  • Explore the implications of using engineering stress in structural analysis
  • Learn about other material specifications and their stress definitions
USEFUL FOR

Engineers, material scientists, and students in mechanical or civil engineering who require a clear understanding of material strength specifications and their applications in design and analysis.

Are the yield and ultimate strengths that you find in specs (e.g. ASTM A36) true stress or engineering stress values?

Thanks!
