Questions and Answers

How is the yield point determined for steel with a well-defined yield point?

  • By conducting multiple tensile tests
  • By applying a 0.2% offset
  • By measuring stress at a tensile strain of 0.0035
  • By the drop or halt of the gage of the tensile testing machine (correct)
  • What method is used to determine the yield strength for steel without a well-defined yield point?

  • Stress measurement at a tensile strain of 0.0035
  • Drop or halt of the gage of the tensile testing machine
  • Conducting hardness tests
