The loss of stress with time at constant strain in steel is called
The loss of stress with time at constant strain in steel is called
Show Hint
- Relaxation is important in prestressed concrete to prevent excessive loss of tension in tendons.
Updated On: Feb 27, 2025
- relaxation
- creep
- shrinkage
- ductility
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Definition of relaxation.
- Relaxation occurs when stress reduces in a material even when strain remains constant.
- This is significant in prestressed concrete and high-strength steel.
Step 2: Difference between relaxation and creep.
- Relaxation happens under constant strain.
- Creep happens under constant stress.
Thus, the correct answer is (A) relaxation.
