Strain Energy Of Torsion

1 min reading time..

Torsion is the twisting action of a body around the longitudinal axis, because of a moment application. Shear stresses occur because of the torsion. You can find the calculation of the shear stresses because of the torsion in Mechanical Base. 

Here, we explain the strain energy originated from these torsional shear stresses. 

What Is The Strain Energy Of Torsion

Strain energy is the total energy on a body that undergoes torsional twisting. It is calculated with the equation below; 

As you see above, the equation of the strain energy of torsion is very simple. In this equation; 

𝜏max is the maximum shear stress occurred on the body that undergoes torsion. 

G is the shear modulus of the material of the body. 

V is the total volume of the body that undergoes torsion. 

Strain Energy Of Torsion Calculator

The use of the calculator above to calculate the strain energy of torsion on a body is very basic. You just need to enter the required values inside the brackets then click on the ‘Calculate!’ button to see the result. If you want to make another calculation, click on the ‘Reset’ button then re-enter the values. 

You can enter the values in the unit recommendations inside the parentheses both in SI and US Customary units. If you do not have consistent sets of units, you can use the MB-Unit Converter tool.


The explanation and calculation of the shear strain energy due to torsion are very simple as you see above. 

Mechanical Base does not accept any responsibility for calculations made by users in calculators. A good engineer must check calculations again and again.
