Dr. Haghgouyan specializes in the failure analysis and mechanical behavior of engineering materials, with specific expertise in metallurgy, materials characterization, and deformation mechanisms of metals. He has particular interest in assessing fracture and fatigue behavior of NiTi-based shape memory alloys (SMAs) using novel experimental test methods and computational mechanics. His expertise includes fracture mechanics-based analyses, materials characterization using a variety of techniques including mechanical testing, metallography, optical and electron microscopy, and finite element modeling.

Prior to joining Exponent, Dr. Haghgouyan was a postdoctoral research associate at Texas A&M University, where he worked on development and characterization of durable and damage tolerant SMAs for use in actuation applications. Specifically, he studied structural and functional fatigue of high-temperature SMAs, such as NiTiHf, and conducted experiments under various thermomechanical loadings for model calibration/validation.

Dr. Haghgouyan completed his Ph.D. in Materials Science and Engineering at Texas A&M University, where he studied deformation and fracture of NiTi-based SMAs. His work focused on developing and modifying experimental test methods to measure mechanical properties, such as fracture toughness and fatigue crack growth rate, in phase transforming materials using Nitinol as the choice material. Additionally, he leveraged computational tools to simulate and predict failure by computing fracture mechanics parameters using commercial finite element software (Abaqus).
