Strain hardening of structural steel means
Show Hint
- experiencing higher stress than yield stress with increased deformation
- strengthening steel member externally for reducing strain experienced
- strain occurring before plastic flow of steel material
- decrease in the stress experienced with increasing strain
The Correct Option is A
Solution and Explanation
In structural steel, this leads to an increase in the yield strength of the material as it is deformed beyond its yield point, which is an important feature in many structural applications.
Thus, the correct answer is that strain hardening means experiencing higher stress than yield stress with increased deformation.
Final Answer: experiencing higher stress than yield stress with increased deformation
