Question

relationship between volumetric strain and linear strain

Answer 1

Linear strain of a deformed body is defined as the ratio of the change in length of the body due to the deformation to its original length in the direction of the force while 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. we see that they both have a ratio in change of either in volume or length 

Answer 2

Thanks for the question!

It is definitely a very interesting question to solve and do some brainstorming.

**************************************************

Linear strain is the  ratio of the change in length of the body due to the deformation to its original length in the direction of the force while Volumetric strain is the ratio of the change in volume of the body to the deformation to its original volume.
