Abstract
The expansion of shaped pipe in oilfield borehole repair by means of various shaped draw bars is modeled by the finite-element method. The optimal draw-bar configuration is determined from the pressure on the tool and the effective strain. Recommendations are made regarding the shape of the draw bar.
