Toughness:
The ability of a material to absorb energy in plastic deformation till the point of fracture is known as toughness. Toughness is indicated by the total area under the stress-strain curve up to the fracture point.Eg. Copper has higher toughness than Cast iron.
Resilience:
The ability of a material to absorb energy under elastic deformation and to recover this energy upon removal of load is termed resilience. Resilience is indicated by the area under the stress-strain curve till the point of elastic limit.
Creep:
It is a deformation of a material due to the constant load for a long period of time. It is the time and temperature-dependent property of a material.
Fatigue:
When a body is subjected to repeated and fluctuating load it tends to develop a characteristic behavior under which failure occurs which is referred to as fatigue.
