Strain energy is a form of potential energy. Work done to distort an elastic member is stored as strain energy. Some energy may be lost in plastic deformation of the member and some may be converted into heat instead of stored as strain energy, but the rest is recoverable.
A spring is an example of a storage device for strain energy.

What is proof Stress for Steel?
proof stress can be found by referring to the stress/strain curve at the point where strain is = 0.2% original volume (the material has grown 0.2% in volume) proof stress will be given as a measurement of energy (MPa,KPa etc.) as it specifically refers to the amount of energy required to stress the material to 0.2% its original volume.
Formula for total energy?
kinetic energy+potential energy=total energy
What type of energy can be converted into mechanical energy?
electrical energy
What is a mechanical energy?
Mechanical energy is the sum of potential energy and kinetic energy in a system. It represents the energy associated with the motion and position of an object. Potential energy is stored energy based on an object's position, while kinetic energy is the energy of motion. In a closed system, mechanical energy is conserved, meaning it remains constant if no external forces do work on the system.
How to calculate strain energy in a material?
To calculate strain energy in a material, you can use the formula: Strain Energy 0.5 x Stress x Strain. Stress is the force applied to the material, and strain is the resulting deformation. Multiply stress and strain, then divide by 2 to find the strain energy.
Could you show the derivation of elastic strain energy per unit volume?
The elastic strain energy per unit volume, also known as the strain energy density, can be derived by integrating the stress-strain curve over the strain range. The area under the stress-strain curve represents the work done on the material, which is equivalent to the strain energy stored. By dividing this strain energy by the volume of the material, the strain energy density per unit volume can be obtained.
Example of strain energy?
An example of strain energy is when a rubber band is stretched. As it is stretched, potential energy is stored within the rubber band in the form of strain energy. When the rubber band is released, this strain energy is converted back into kinetic energy as it snaps back to its original shape.
What is another name of strain energy?
Potential energy.
How potential energy related to strain energy?
Strain energy is a form of potential energy that is stored within a material when it is deformed or strained. When a material is subjected to external forces causing deformation, the potential energy stored in the material is referred to as strain energy. This energy is released when the material returns to its original shape, such as when a spring is compressed and then released.
Find an expression for the energy density in terms of stress and strain?
The expression for the energy density in terms of stress and strain can be expressed as ρe.
What is strain energy theory?
The strain theory is a state of deviation from bond angle of a normal tetrahedral angle.
What is strain energy due to torsion?
Strain energy due to torsion is the energy stored in a material when it is twisted under a torque load. It is calculated as the integral of shear stress and strain over the volume of the material. This energy represents the ability of the material to deform plastically under torsional loading.
What are definitions of energy?
One definition of energy is the ability to do work. Another is the fuel for life.
What is the unit of strain energy?
The unit of strain energy is the joule (J), which is equivalent to a force of one newton applied over a distance of one meter. Strain energy represents the energy stored within a material due to deformation caused by applied forces or stresses.
Energy stored by a stretcher or compressed object?
it is called strain energy
Can you name 2 objects which contain strain energy?
A stretched rubber band and a compressed spring both contain strain energy.
