Elastic body
Definition: The property on account of which a body regain it's original size and shape on removal of external deforming force is called as elastic body.
Process: It is reversible.
Ductility: It is less ductile in nature.
Modulus of elasticity: The ratio of stress to strain is low or equal.
Toughness: They have the ability to absorb energy up to fracture.
Bonds: The molecular bonds do not get fractured.
Shape and size: The shape and size does not change permanently.
Example: Rubber.
Plastic body
Plastic body: The property on account of which a body doesn't regain its original size and shape on removal of applied force is called as plastic body.
Process: it is irreversible
Ductility: They are highly ductile in nature.
Resilience: They have low yield strength.
Modulus of elasticity: The ratio of stress to strain is high.
Toughness: They do not have the ability to absorb energy up to a fracture.
Bonds: The molecular bonds are fractured.
Shape and size: The shape and size changes permanently.
Example: Plasticine
