1.24 Elastic behaviour
Describe elastic behaviour as the ability of a material to recover its original shape after the forces causing deformation have been removed
Concept essentials
- Elastic behaviour requires recovery after the deforming force is removed.
- A material can stretch and still be elastic if it returns to its original length.
- The elastic limit is the boundary beyond which permanent deformation can occur.
- A graph returning to zero extension during unloading shows elastic recovery.
