Job Description 

The objective of the internship is to analyze and optimize the design of a downhole tool used for oil and gas drilling operations.  The objective of the first phase is to develop a coupled thermomechanical model for elastomers in ABAQUS or COMSOL to capture the temperature increase in the elastomer components of the tool due to the viscoelastic and frictional heat dissipated. In the second phase of the project, the thermomechanical model will participate in a coupled Fluid-Solid Interaction (FSI) model, providing appropriate boundary conditions to the flow. In parallel, the candidate is expected to optimize the design of the elastomeric components to maximize life and performance.

Requirements 

1.      Ph.D. degree in Mechanical Engineering, Aerospace Engineering, Civil Engineering, or Engineering Mechanics

2.      In-depth understanding of continuum mechanics, elastomer behavior, finite element method, engineering design concepts, and materials engineering. Sound knowledge of hyperelasticity, viscoelasticity and temperature effects on these.

3.      Experience in modeling and simulation of elastomers subjected to large mechanical and thermal deformations.

4.      Solid knowledge of ABAQUS is essential. Experience in COMSOL and/or Ansys Classic/Workbench is a plus.

5.      Experience in developing user subroutines for ABAQUS
