Project Description
To create simulation pipeline that can be used to predict residual stress development and distortion in complex additive manufacturing (AM) components. The effort will include using finite element software (e.g. Abaqus) to model the solidification of additively manufactured materials based on AM processing parameters and material thermal profile versus time. Experimental residual stress development that has been previously measured via energy dispersive x-ray diffraction techniques will be used to calibrate and validate the modeling efforts.
Tasks and Responsibilites
1) Develop pipeline for creation of Abaqus input file containing part finite element mesh, loading & boundary conditions versus time, and temperature-dependent material properties/parameters.
2) Develop automated job submission script utilizing slurm/unix commands to set Mortimer HPC environment and number of cpus to use for AM process simulations.
3) Develop Python or Matlab script to read in and compare experimental and simulation results.
4) Develop pipeline to update material parameters for calibration/validation based on the comparison of experimental and simulation results.
5) Report research findings periodically to Academic mentor and within poster session at Undergraduate Research Symposium.
