About

Leroy Gardner is a leading figure in structural engineering, whose research focuses on the intersection of advanced manufacturing and steel construction. His primary contributions lie in understanding the mechanical behavior and fracture mechanics of wire arc additively manufactured (WAAM) steels, a field critical for the future of modular building systems. Gardner’s most influential work, a 2023 study on fatigue crack growth in WAAM steels (72 citations), provides foundational data for ensuring the long-term durability of 3D-printed steel components. He has also advanced the practical application of these materials through a comprehensive review of optimized additively manufactured steel connections for modular buildings (19 citations). Most recently, his 2025 study on ductile fracture (12 citations) has been pivotal, demonstrating that WAAM steel exhibits superior fracture ductility compared to conventional steels. By developing and validating sophisticated numerical models that accurately predict fracture behavior under various stress states, Gardner is equipping engineers with the tools needed to design safer, more resilient structures. His work is not only pushing the boundaries of what is possible with additive manufacturing but is also laying the critical groundwork for its safe and widespread adoption in the construction industry.
