What is Elliptical/Parabolic Steel Bending?

Elliptial/Parabolic steel bending occurs when the material is bent in one plane, but the radius changes throughout the arc. A radius is the line segment that joins the center of a circle with any point on the materials circumference (see Center-Line Radius). Arc is defined as the curved portion of a bend. Below are some examples of elliptical/parabolic bends.
