High Fidelity Microstructure-Sensitive Modeling of Advanced Materials

Engineering & Applied Science (College of) / Mechanical Engineering

Project Description

To create simulation pipeline that can be used to predict the evolving mechanical behavior at the microstructure scale of a material that is subjected to repetitive (fatigue) loading. The effort will include using microstructure instantiation (Dream.3D) and finite element (Abaqus) software programs to model the elastic/plastic deformation and fatigue crack growth of the material as a function of number of cycles. Experimental lattice strain information obtained from high energy x-ray diffraction microscopy techniques will be used to calibrate and validate the developed model. 

Tasks and Responsibilites

1) Develop pipeline for creation of Abaqus input file containing part finite element mesh, microstructure instantiation, loading & boundary conditions versus time, and microstructure-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 microstructure-sensitive modeling efforts. 3) Develop Python or Matlab script to read in and compare experimental and simulation results using an appropriate volume-averaging scheme. 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.
