Mr. Babic specializes in mechanical design, accident reconstruction, and failure analysis. Mr. Babic makes extensive use of finite element modeling to evaluate structural, thermal, and fluid behavior. He performs corrosion, fatigue, and fracture mechanics analyses of mechanical and electro-mechanical systems and components, as well as full-scale and laboratory testing, instrumentation, and data acquisition. Mr. Babic is experienced in metallurgical failure analyses using macroscopic and microscopic techniques for fracture surface and microstructure characterization. He is also experienced in investigations involving heavy equipment such as scissor lifts, boom lifts, cranes, as well as collapses of large structures. Within those investigations he performed structural analysis, as well as analysis of hydraulic, electrical, and control systems.
Mr. Babic’s research includes powder metallurgy alloys, compaction and sintering process analysis, sintered material analysis, material and fracture surface characterization, material imperfection analysis, and thin film analysis utilizing optical and electron microscopy, atomic force microscopy, energy dispersive X-ray spectrometry, Auger electron spectrometry (AES), electron spectroscopy for chemical analysis (ESCA), and inductively coupled plasma – mass spectrometry (ICPMS) for analyses of trace elements.
Mr. Babic has evaluated and developed enabling technologies in semiconductor manufacturing such as supercritical carbon dioxide cleaning methods and atomic layer deposition. He is experienced in clean room protocols and safety procedures, and in pressure vessel and piping system design, fabrication, safety issues, and relevant codes.
Mr. Babic is also experienced in vehicle design, testing, and analysis. He has participated in a racecar series and has direct experience with race preparation, vehicle systems, dynamics, and mechanics. He is currently completing a Ph.D. in Mechanical Engineering, at Arizona State University, with emphasis on material behavior under shock loading.
