Dr. Nirankari’s areas of expertise include failure analysis, metallurgy, fracture, welding, finite element modeling and materials characterization. Dr. Nirankari has conducted research and failure analysis of metals and welds involving both experimental and computational approaches. He has applied his expertise to a range of engineering fields, including automotive, aerospace, consumer electronics and utilities. He has experience with mechanical testing techniques, fractography, metallurgical and microstructural analysis, non-destructive evaluation, microscopy and computational mechanics.

Dr. Nirankari has extensive experience performing mechanical testing as well as microstructural analysis via optical microscopy, scanning electron microscopy (SEM), electron backscattered diffraction (EBSD), transmission electron microscopy (TEM) and energy dispersive X-ray spectroscopy (EDS). He is also skilled in computed tomography (CT). His computational expertise lies in use of finite element modeling. He has extensive experience with commercial finite element software (Abaqus) and computer aided design software (SolidWorks).

During his graduate study at the University of Michigan, Dr. Nirankari’s research included the use of mechanical testing to understand the crack initiation and small crack propagation behavior of aluminum spot welds and finite element modeling to predict the weld lifetime. As an undergraduate, Dr. Nirankari’s research focused on improving the efficacy of plasma sprayed thermal barrier coatings for turbine blades.
