Biography
Dr. Gowayed is the Chair of the Department of Human Centered Design. His research work focuses on developing computational models and experimental techniques to further the understanding of the mechanical and thermal behavior of polymer and ceramic matrix composites. He has been successful in forming research consortia with universities, industries, national laboratories, and small businesses, and leading research efforts funded by NASA, AFRL, DoE, DoC, DHS, Pratt & Whitney, Rolls-Royce and Goodrich. He documented his research efforts in many refereed publications, presentations, book chapters and most recently a book on Ceramic Matrix Composites. He also compiled some of his research work into the computer algorithm “Graphical Integrated Numerical Analysis pcGINA©” which is currently used by many aerospace companies and government agencies to design polymer and ceramic matrix composites.
He teaches classes in mechanics of composite materials and fabric structures for Seniors and Graduate Students and Research Methods for Graduate Students. He is interested in novel teaching methods and cross-disciplinary educational paradigms and developed and taught non-traditional learning experiences.
Research Interests
- Mechanics of composite materials with emphasis on deformation mechanisms and structure property relationships
- Use of composite materials in turbine engines and nuclear applications
- Time-dependent response of polymer and ceramic matrix composites
- Damage progression and the estimation of life for ceramic matrix composites
- Effect of oxidation kinetics and elevated temperature on the mechanical response of ceramic matrix composites
- Manufacturing and testing of polymer matrix composite structures
- Novel composite materials for the 400-800 oC design range
Dr. Gowayed developed and taught classes on Introduction to Engineering for freshmen students, Mechanics of Flexible Structures, Fiber reinforced materials and Senior Design for seniors, Numerical methods in Design for juniors, and Advanced mechanics of flexible structure and Mechanics of fiber reinforced materials for graduate students. He also taught Research Methods for new graduate students.
Additionally, he worked on the design of undergraduate and graduate curriculums, prepared of ABET assessment reports, and served as the Graduate Program officer.
