Defined Types of Strain
- The longitudinal strain is defined as the ratio of the new length to the initial length.
- The lateral strain is defined as the difference between the original diameter and breadth and the changed diameter and breadth.
- The ratio of the volume change of the body to the deformation to its initial volume is known as the volumetric strain of a deformed body.
- The strain that results from a shearing operation is known as shear strain. When the body is subjected to external shearing action, it distorts through this angle, measured in radians.
The unit of strain is _____? (I) m (II) m2 (III) m-1 (IV) strain is dimensionless
The strain unit has no dimensions. It is defined as the ratio of the changed dimension to the actual dimension. The Poisson's ratio is the ratio of lateral strain to longitudinal strain.
