Interface Strength Modeling in FGMs
This study focused on modeling and experimentally validating the interface strength of Functionally Graded Materials (FGMs) manufactured using the Fused Filament Fabrication (FFF) process. Interface zones in multi-material printed parts often experience stress concentrations, cracking, or delamination, especially with abrupt material changes. This project aimed to address those issues by using gradient transitions and multi-scale numerical modeling to improve reliability.

Functionally Graded Additive Manufacturing
Functionally Graded Additive Manufacturing (FGAM) has been a core focus of my research, particularly during my doctoral work at Tennessee Tech University. The goal of this work was to explore the use of low-cost Fused Filament Fabrication (FFF) techniques to design, fabricate, and characterize multi-material structures with functionally graded properties.
