Quick Strain is the resulting deformation due to stress. It is a dimensionless quantity. Normal strain is often referred to as just strain, even though there are other types as given below.
Strain describes the resulting deformation due to stress. Strain is the amount of "give" or deformation caused by stress, such as deflection in bending, elongation in tension, contraction in compression, and angular twist in torsion. The general equation for strain is:
(Eq1)
strain =
change in length
original length
The quantity "change in original length over original length" is the "unit elongation," or "strain," which is dimensionless.
