Question

Write short notes on Volumetric Strain.

Answer 1

Answer:

Explanation:

Volumetric stress is a particular stress state in which all three directions are uniformly loaded. This could be compressive or tensile, but it is most often associated with compressive stress states.

Answer 2

Volumetric strain: Volumetric strain of a deformed body is defined as the ratio of the change in volume of the body to the deformation to its original volume. If V is the original volum and dV the change in volume occurred due to the deformation, the volumetric strain ev induced is given byConsider a uniform rectangular bar of length l, breadth b and depth d as shown in figure. Its volume V is given by,This means that volumetric strain of a deformed body is the sum of the linear strains in three mutually perpendicular directions.
