The ability of a material to absorb energy till the elastic limit

SOLUTION

Plasticity: It is the property of a material which retains the deformation produced under load permanently. Thus, it is a property of material which allows it to deform without fracture

Toughness: The ability of the material to withstand stress (resist fracture due to high impact loads) without fracture is known as toughness. It is defined as the ability to absorb energy in the plastic state

Elasticity: It is the property of a material to regain its original shape after deformation when the external forces are removed.

Ductility: The property of the material that allows it to be drawn into wires or elongated before failure is known as ductility.

Brittleness: The property of a material that produces fracture without any appreciable deformation is known as brittleness. It is the opposite of toughness.

Resilience: It is the total strain energy stored in a given volume of a material within elastic limit. On removal of load this energy is released. In other words, it is the area under load deflection curve within elastic limit.
