Question

What are the types of strain?

Answer 1

There are three types of strain:

1. Longitudinal strain: A longitudinal strain is defined as the change in the length to the original length of an object.
   $\mathrm{Longitudinal}\mathrm{strain}=\frac{\mathrm{change}\mathrm{in}\mathrm{length}}{\mathrm{original}\mathrm{length}}$
2. Volumetric strain: Volumetric strain is the ratio of change in volume to the original volume of an object.
   $\mathrm{Volumetric}\mathrm{strain}=\frac{\mathrm{change}\mathrm{in}\mathrm{volume}}{\mathrm{original}\mathrm{volume}}$
3. Shearing strain: The shear strain is the term used to describe the angle tilt that tangential stress causes in the body. Shear strain is measured as a modification in angle between lines that were originally perpendicular.
