Proof resilience:
The strain energy stored in a body due to external loading, within the elastic limit, is known as resilience and the maximum energy which can be stored in a body up to the elastic limit is called proof resilience.
Modulus of resilience:
Modulus of resilience is defined as proof resilience per unit volume. It is the area under the stress-strain curve up to the elastic limit.
Toughness:
It is defined as the ability of the material to absorb energy before fracture takes place.
- This property is essential for machine components which are required to withstand impact loads.
- Tough materials have the ability to bend, twist or stretch before failure takes place.
- Toughness is measured by a quantity called modulus of toughness. Modulus of toughness is the total area under the stress-strain curve in a tension test.
Flexure rigidity:
- It is a measure of the resistance of a beam to bending, that is, the larger the flexural rigidity, the smaller the curvature for a given bending moment.
- EI = Flexural rigidity

Proof resilience is the correct answer. Proof resilience is defined as the maximum energy that can be absorbed up to the elastic limit without causing permanent deformation or distortion of a material. It is an important property to consider when designing materials that need to withstand impact or shock loading.
Proof resilience is a measure of a material's ability to absorb energy and return to its original shape after being deformed elastically. It is a measure of the area under the stress-strain curve up to the elastic limit. The elastic limit is the maximum stress that a material can withstand without permanent deformation.
To better understand why proof resilience is the correct answer, let's compare it with the other options:
a) Toughness: Toughness is a measure of a material's ability to absorb energy and plastically deform before fracturing. It represents the total energy absorbed by a material up to the point of fracture. While toughness is an important property, it is not specifically related to the elastic limit and permanent deformation.
b) Modulus of resilience: The modulus of resilience is a measure of a material's ability to store elastic energy. It represents the area under the stress-strain curve up to the elastic limit. It is related to the proof resilience, but it does not specifically refer to the maximum energy that can be absorbed without causing permanent deformation.
c) Proof resilience: As mentioned earlier, proof resilience is the correct answer. It represents the maximum energy that can be absorbed up to the elastic limit without creating permanent distortion. It is a measure of a material's ability to absorb energy and return to its original shape after being elastically deformed.
d) Flexural rigidity: Flexural rigidity is a measure of a material's resistance to bending. It is not directly related to the maximum energy that can be absorbed without permanent deformation.
In conclusion, proof resilience is the correct term for the maximum energy that can be absorbed up to the elastic limit without causing permanent distortion. It is an important property to consider when designing materials that need to withstand impact or shock loading.
