- demonstrate something that embodies threshold restoration behavior -

Threshold:
Often perceptual distinctions in a certain context have a threshold to 
them. That is, when you increase or decrease them beyond a certain 
value they will create a permanent change in the shape of a material 
as a result of the application of an applied stress. The work done in 
deforming the material is irreversible.

The following animation demonstrates two types of threshold behavior. 

Plastic deformation:

The first behavior [A] illustrates a deformation as a result of 
an impact by an external force. Once applied, the force alters the 
molecular make up of the surface area while the neglected side is 
slightly unaffected. The end result of the impact alters the physical 
state of the material permanently.

The second behavior [B] of the animation describes deformation 
due to uniformly high heat transfer. This phenomenon has the ability 
to alter the entire molecular make up of the materials. Unlike 
behavior [A], where the alteration takes place only on the 
concentrated area, behavior [B] has the capability to uniformly 
affect the entire region.
