What is the difference between elastic and plastic deformation?

Elastic deformations of a solid are entirely recoverable once the stress is removed. No part of the object under stress has undergone permanent deformation. Plastic deformation of a solid are permanent. In fact to reach plastic deformation you always have to begin with elastic deformation.

In this regard, what is the difference between ductile and brittle?

Ductility is the ability of a material to withstand tensile force when it is applied upon it as it undergoes plastic deformation whereas Brittleness is the opposite of ductility as it refers to the ability of materials to break into pieces upon application of tensile force without any elongation or plastic deformation.

How is ductile deformation different from elastic deformation?

What is the difference between brittle and ductile rocks? The amount of elastic deformation a material can take before ductile deformation. In ductile deformation, the strain remains when stress is removed, but in brittle deformation, the object fractures.
