Postdoctoral Researcher

• Execute an industry funded project with Juggerbot3D to develop additive manufacturing capabilities for fiber reinforced thermoset resin systems.
• Support the Composites Additive Manufacturing and Simulation Consortium (CAMS) at the Composites Manufacturing and Simulation Center through simulation, characterization, and validation for printing with various thermoplastic composites.
• Prepare reports and publications that will be submitted to archival journals, contributing to the preparation of funding proposals.

Ph.D. Thesis

• Modeled the flow of cylindrical pellets in a single screw extruder using LIGGGHTS, a discrete element method open-source code implement in C++, and used Paraview for pellet trajectory visualization.
• Validated pellet motion in the solid-conveying zone of a single screw extruder for starve-fed extrusion of 40% CF-PPS by building an extruder system with acrylic barrel for visual pellet tracking.
• Created a sequentially coupled discrete element – finite element (DEM-FEM) framework to capture heat-transfer and melting of a single pellet in ABAQUS based on contact information obtained from LIGGGHTS.
• Extended melting and crystallization kinetics model of semi-crystalline 40% CF-PPS and implemented in ABAQUS heat-transfer simulations through user-subroutine UMATHT.
• Developed analytical models based on beam theory for partially molten pellet deformation and fiber-breakage in the melting zone of a single screw extruder.

Graduate Research Assistant

• Collaborated with the additive manufacturing team to develop material cards for short-fiber reinforced polymer composites such as 50% CF-PPS, 25% CF-PESU, and 25% CF-PSU to enable simulations.
• Performed various experiments to characterize the thermo-mechanical and microstructural properties of orthotropic viscoelastic materials used in extrusion deposition additive manufacturing (EDAM)
• Wrote MATLAB codes to measure and obtain the fiber-orientation tensor and fiber-length distribution from optical micrographs using the image-processing toolbox.
• Validated residual stresses and deformation of additively manufactured geometries using Additive-3D, an in-house physics-based simulation software.
• Investigated the effect of printing parameters such as bead aspect ratio, layer height, and stretching ratio on the effective mechanical properties of printed parts and validated
