1.31 Describe elastic behaviour as the ability of a material to recover its original shape after the forces causing deformation have been removed.

Elastic behavior is the ability of a material that can return to its normal shape after forces that caused deformation have been removed.

Eg when an (initially elastic) object no longer does this, it has reached elastic limit.

Figure 1: A spring, for example, shows elastic behavior.

Figure 2: A spring that has been stretched past its elastic limit. This will not return to its original shape :(
