Mechanical components and structures made of composite materials are extensively being used in mechanical, automotive, aerospace, power generation and transmission including green technology, sporting equipment, medical instruments, and civil infrastructure engineering applications. The applicant has developed a long-term research program with the goal of conception, design and development of innovative high-performance composite components and structures for practical existing and new applications. The long-term objectives of the applicant's on-going research program have been: (1) To conceptualize safe, reliable, cost-effective, innovative and high-performance composite components and structures; (2) To determine accurately the critical failures, dynamic response, and dynamic instabilities of such components and structures; (3) To develop optimal designs for desired reliability and performance requirements of such components and structures. Over the next 5 years, intensive and innovative research on a certain specific class of advanced composite structures, called "tapered composite structures" will be conducted. Emphasis will be placed on flat and curved tapered composite beams and plates. Samples of such composite beams and plates will be manufactured and tested for vibration response and failures. Advanced computational modeling and the stress, dynamic and failure analyses of such structures will be conducted. The cost-effective design of innovative composite beams and plates will be performed. A number of undergraduate and graduate students will be recruited and trained in the research. Industrial collaboration and international networking will be actively sought and used. The proposed research will serve significantly the Canadian engineering industries in making them even more globally competitive and profitable, and hence contributes significantly to the economic development of Canada. It also serves the Canadian academic sector in attracting and training globally-competitive, highly skilled, and very talented students and engineers. High quality and cutting-edge research results will be generated and published in international research media and meetings.
