(a) Young’s modulus

(b) Modulus of resilience

(c)Resilience

(d) Proof of resilience

Modulus of resilience is known as total strain energy stored in a body. Strain Energy is the internal labour required to distort the body as a result of externally applied forces and is known as the strain energy of the member. Strain energy = ½ x stress x strain x volume

### Total Strain Energy Stored in a Body

• Resilience: The total strain energy that a given volume of material can hold within its elastic limit is known as resilience. This energy is released when the burden is removed. It is, therefore, the region under the load-deflection curve that is contained inside the elastic limit.
• Proof resilience: Proof resilience is the highest amount of energy that can be held in a body up to the elastic limit.
• Modulus of resilience: Proof resilience per unit volume is the definition of the modulus of resilience. Up to the elastic limit, it is the region under the stress-strain curve.

Summary:

## What is known as total strain energy stored in a body? (a) Young’s modulus (b) Modulus of resilience (c)Resilience (d) Proof of resilience

Total accumulated strain energy in a body is referred to as the modulus of resilience. It can be defined as proof of resilience per unit volume. Resilience is the total strain energy that can be hold by a given volume of material within its elastic limit.
