  • Drill Master: Understanding Bend Radius - Trenchless ...

    2002-6-1u2002·u2002One of the keys to these calculations is bend radius. Bend radius is a term that many people use, but few understand. Often times it is confused with 'the number of feet needed to make a 90-degree turn.' Understanding bend radius and how to use it to maximize profits and minimize downtime is of the utmost importance to the driller.

    2021-8-3u2002·u2002The fact that you are bending a rod to a constant radius means that by definition, there is no shear deformation. This makes the assumptions behind Euler-Bernoulli bending valid.
