Determination of Pipe Pullback Load for Horizontal Directional Drilling (HDD) Crossings by Finite Element Method

This paper put forward a new method to determine the tensile loading during the installation of steel pipe using the horizontal directional drilling (HDD). There are several methods being currently used. Advantage and disadvantages of those methods are discussed. The paper describes a commonly used Finite Element technique along with sophisticated material model, which deals with softening and failure of geomaterials. It has been shown that...
