RESEARCH SUMMARY

Professor Mohamad Qatu’s is passionate about the use of mechanics to solve engineering design problems, particularly in the area of vibrations. He worked on composite plates and shells and developed a theory for the analysis of deep laminated shells. His theory is proven to be more accurate than higher order theories for various types of shells. Dr. Qatu’s book on vibration of laminated shells and plates is the first in the field. In addition, Dr. Qatu applied mechanics principles to study fluid born noise phenomenon in power steering lines. His apparatus and methods are widely used in the auto industry today. Dr. Qatu’s work on various noise and vibration and harshness (NVH) phenomenon in automotive engineering is also recognized and frequently referenced in the engineering community. In particular, he is recognized for his work on driveline systems, engine mounts, exhaust systems, as well as others. Dr. Qatu used computer aided engineering tools like finite element method and others in his research.

Dr. Qatu has published more than 100 articles, most of which are in refereed journals. He is the editor in chief of the International Journal of Vehicle Noise and Vibration and on the editorial board on Composite Structures. He also has two patents registered to his credit on noise suppression. He is a Fellow in both SAE and ASME. He is a registered professional engineer in various states.
