SUMMARY

The discussion focuses on calculating Young's Modulus of Elasticity for 0.1% carbon steel using tensile test results. The user provided specific values: an area of 20 x 10-6 m2, a yield force of 6009 N, and a length increase of 0.537 mm. The calculated Young's Modulus was 14.32 x 109 Pa, significantly lower than the typical value of 207 x 109 Pa. The discrepancy suggests a potential error in unit conversion or input values.

PREREQUISITES
  • Understanding of tensile testing and material properties
  • Familiarity with Young's Modulus and its significance in materials science
  • Knowledge of unit conversions, particularly between metric units
  • Basic mathematical skills for calculating stress and strain
NEXT STEPS
  • Review unit conversion techniques for force and area in material calculations
  • Study the principles of tensile testing and how to accurately measure yield force
  • Learn about common values of Young's Modulus for various materials, particularly steels
  • Explore the effects of carbon content on the mechanical properties of steel
USEFUL FOR

Materials scientists, mechanical engineers, and students involved in material testing and analysis, particularly those focused on the mechanical properties of carbon steel.

I am trying to calculate youngs modulus of elasticity for results from a tensile test but can't seem to get a figure close to that of the common figure for the material

Material 0.1% carbon steel
Area = 20 x 10-6
Yield force = 6009N
Length increase at yield force = 0.537mm = 0.000537m
Original length = 25.6mm = 0.0256mE = σ/ε

E = (6006/20x10-6) / (0.000537/0.0256)
E = 14.32 x 109
Typical value = 207 x 109

Iv obviously went very wrong somewhere but i don't know where

Thanks

Your calculations seem fine, what is the unit of the area? You can also make sure that the force is in N, not in kN or something.
 
The unit of area is m^2, and the force was 6.009 KN so 6009 N. Its way off the typical value though, it doesn't make sense?
