Conceptual (elastic Limit)
Easyphysics
Beyond elastic limit a material?
Select the correct option:
Solution
Incorrect! Answer:
Undergoes permanent deformation
- Elastic Range: Within the elastic limit, a material returns to its original dimensions after the deforming force is removed.
- Elastic Limit: This is the maximum stress that can be applied to a material without causing permanent (plastic) deformation.
- Plastic Region: If stress exceeds this limit, atomic planes start sliding past one another permanently.
- Result: Even after removing the load, the material retains a 'set' or permanent strain. It has undergone permanent deformation.
