- Strain energy is the potential energy absorbed by the body due to the deformation or strain effect. It is denoted by the symbol uppercase letter ‘U’. The strain energy absorbed by the material is equal to the work required to create the deformation in the object. Therefore we can say that, Strain energy = Deformation work

Strain energy. In physics, the elastic potential energy gained by a wire during elongation with a tensile (stretching) or compressive (contractile) force is called strain energy. For linearly elastic materials, strain energy is: where σ is stress, ε is strain, V is volume, and E is Young's modulus :
Mar 17, 2023 · Strain energy refers to the energy stored in a system due to the deformation or distortion of its components. When an object is subjected to external forces that cause it to change its shape or size, it absorbs energy to resist the deformation. This energy is stored in the material as strain energy.
Jan 25, 2023 · Strain Energy: Strain energy is defined as the energy stored in any material due to deformation. When a deformable structure, such as rubber, spring, metals, etc., stretches, then it stores a type of energy called strain energy. In many such cases, we can turn back this energy into kinetic energy relatively in an easy way.

- Q.2. What does the area under stress vs strain graph represent?Ans: Area under stress vs strain graph represents the work required to stretch the material. The area under the curve up to the elastic limit repre...
- Q.3. What is the SI unit of strain energy?Ans: Strain energy has the unit of energy or work. Its SI unit is J or Nm. The dimensional formula of strain energy is ML2 T−2.
- Q.4. If the value of stress is doubled, what will be the effect on strain energy?Ans: We know that the formula of strain energy Is given by, U=12×(Stress)2E×volumeofmaterial So, when the stress is doubled, then the strain energy...
- Q.5. For the same stress, does the strain energy will depend on the type of material?Ans: The formula of strain energy can be written as, U=12×(Stress)2E×volumeofmaterial Thus from the above formula, we can observe that the strain e...
Definition of Strain Energy. Strain energy is a type of potential energy that is stored in a structural member as a result of elastic deformation. The external work done on such a member when it is deformed from its unstressed state is transformed into (and considered equal to the strain energy stored in it.
Strain Energy Formula. Strain energy is defined as the energy stored in a body due to deformation. The strain energy per unit volume is known as strain energy density and the area under the stress-strain curve towards the point of deformation.
The strain energy density u is defined as the strain energy per unit volume: E u xx 2 σ 2 = (8.2.13) The total strain energy in the bar may now be expressed as this quantity integrated over the whole volume, U udV V = ∫, 8.2( .14) which, for a constant cross-section Aand length L reads .
