When a acts on an object, the object may change shape by bending, stretching or compressing - or a combination of all three shape changes. However, there must be more than one force acting to change the shape of a stationary object in the following ways:

Bend an object's ends past each other, eg when an archer pulls an arrow back against a bow.

Pull an object's ends apart, eg when a rubber band is stretched.

Push an object's ends together, eg when an empty drinks can is squashed.

deformation is reversed when the force is removed

deformation is not fully reversed when the force is removed - there is a permanent change in shape

A rubber band undergoes elastic deformation when stretched a little. A metal drinks can undergoes inelastic deformation when it is squashed.
