What is the Elastic Region in the Bolt Tightening Stress/Strain Curve?

• Property of materials to rapidly stretch along its entire length and then form a “neck” after the maximum load has been reached.

• Property of materials to deform under load but return to their original shape and size when load is removed.

• Property of materials to fracture at a certain point when excessive load is applied.

• Property of materials to deform under load but not return to their original shape and size when load is removed.
