What happens to the elastic potential energy when an object is deformed beyond its elastic limit?

The elastic potential energy is converted into other forms of energy when an object is deformed beyond its elastic limit.

When an object is deformed beyond its elastic limit, it means that the object has been stretched or compressed beyond its ability to return to its original shape. At this point, the object has reached its plastic limit and will not return to its original shape even if the force is removed.

When an object is deformed beyond its elastic limit, the elastic potential energy that was stored in the object is converted into other forms of energy. This energy can be dissipated in the form of heat, sound, or even light. For example, when a metal wire is stretched beyond its elastic limit, it may heat up due to the friction between the atoms in the wire.

If the deformation is severe enough, the object may even break or fracture. In this case, the elastic potential energy is converted into kinetic energy as the pieces of the object move apart.

In summary, when an object is deformed beyond its elastic limit, the elastic potential energy is converted into other forms of energy such as heat, sound, or kinetic energy. This is because the object has reached its plastic limit and will not return to its original shape.
