Multiscale thermal-mechanical modeling of severe plastic deformation processes
• Conducted thesis research with Dr.Yung C Shin in multiscale modeling and testing of dynamic deformation processes.
• Developed novel finite element (FEA) models to predict the static and dynamic deformation of components using ABAQUS.
• Modeled processes such as multi-pass compression, hot compression, dynamic tensile loading, orthogonal cutting, laser shock peening, friction stir processing and multi-pass cold rolling.
• Implemented user-defined nonlinear material models in FORTRAN to predict the material behavior at multiple length scales.
• Successfully developed a model that predicted the experimental results with less than 10% error, thereby significantly improving the process modeling workflow without the need to perform expensive experiments.
• Conducted mechanical testing (dynamic tensile loading-Kolsky bar) and microscopic imaging (Ultra-fast imaging and X-ray diffraction) in Argonne National Lab,Illinois to characterize the dynamic response of materials like Copper, Aluminum alloy and Titanium alloy.
