Post-Doctoral Research Associate using ABAQUS/Explicit

A Post-Doctoral Research Associate Position for computational mechanics is open at The University of Tulsa starting in January of 2012. The associate will study the buckling in long drill strings used in the energy industry both analytically and numerically. Applicants must be able to write user-subroutines in Fortran to use within Abaqus/Explicit. Analysis of post-bucking behavior with the ability to predict both lateral and helical buckled shapes is needed.
        Accurately capturing the effects of changing boundary conditions are among the technical challenges for drill string modeling. The purpose of the research is to develop and run Abaqus finite element models to capture the post-buckling behavior of constrained tubular structures comprising the drill string. Both static buckled behavior and dynamic interactions will be predicted as functions of inclination angle, weight on bit, friction, and drillstring composition. The results of these simulations will produce force, torque, rotation, and velocity relationships where the cutting surfaces interact with the rock. The model will be used to help validate algorithms used in drilling dynamics simulations suites. Simulation outputs will be compared to analytical models as well as experimental data that is available.
        The position is for 1 year, with a second year that is likely. The position pays $60,000/year with full benefits. The position is for full time employment. The University of Tulsa enjoys a locale with low cost of living. The project is sponsored by an American energy company that will require monthly updates and quarterly reports. Multiple journal papers are expected as a result of this work. 
        Interested applicants must have a Ph.D. in engineering and command of the Abaqus finite element software. There are no restrictions on nationality, but applicants must be legal to work in the US. 
        To apply please send a cover letter, current resume/CV, and a list of at least 3 references by e-mail to:
