"WebNormal strain Now we consider the resulting deformation. We define the (often just called normal strain strain) on the object to be 𝜖= 𝛿/𝐿. Note that strain is unitless and measures the fractional elongation. In this case of uniform stress, we also have uniform strain, and each element has the same strain. Hooke’s Law.

A normal strain is perpendicular to the face of an element, and a shear strain is parallel to it. These definitions are consistent with those of normal stress and shear stress. Normal strain. For an isotropic material that obeys Hooke's law, a normal stress will cause a normal strain. Normal strains produce dilations.
