any easy defination of strain
I changed my answer.
Is it kk for u?

Normal stress on a body causes change in length or volume and tangential stress produces change in shape of the body. The ratio of change produced in the dimensions of a body by a system of forces or couples, in equilibrium, to its original dimensions is called strain.

Types of Strain
Strain is of three types depending upon the change produced in a body and the stress applied. The three types of strain are
Longitudinal Strain
Volume Strain and
Shearing Strain
Longitudinal Strain : It is the ratio of the change in length of a body to the original length of the body. If L is the original length of a wire or a rod and the final length of the wire or the rod is L+ΔL under the action of a normal stress, the change in length is ΔL
Longitudinal StrainLongitudinal Strain = Change in lengthOriginal lengthChange in lengthOriginal length = ΔL/L
If the length increases due to tensile stress, the corresponding strain is called tensile strain. If the length decreases due to compressive stress, the strain is called compressive strain.
Volume Strain : It is the ratio of the change in volume of a body to its original volume. If VV is the original volume of a body and V+ΔVV+ΔV is the volume of the body under the action of a normal stress, the change in volume is ΔVΔV.
Volume StrainVolume Strain = Change in volume/Change in Original volume
= ΔV/V
Shearing Strain : If is the angle through which a face originally perpendicular to the fixed face is turned. (or) It is the ratio of the displacement of a layer to its distance from the fixed layer.

Normal stress on body cause change in length or volume and tangential stress produces change in shape of the body . The ratio of change produced in a dimension of a body by a system of force or couple in a equilibrium , ro its original dimension is called strain .
strain= change in dimension /original dimension
Types of strain :
Longitudinal strain
Volume strain and
Shearing strain
HOPE THIS IS RIGHT AND IT HELPS YOU .
