Aboudi’s Micromechanics Theories Applied to Multiscale Analysis of Composites
NASA Glenn Research Center in Cleveland, OH has worked with Professor Jacob Aboudi since 1992 to develop and implement his micromechanics theories into a user-friendly software suite. This effort has resulted in the publicly available Micromechanics Analysis Code with Generalized Method of Cells (MAC/GMC) software, along with the coupling of the code with finite element analysis and structural sizing software for multiscale analysis of composite structures. This chapter outlines these methods, discusses why Aboudi’s methods are ideal for use in multiscale analyses, and briefly describes three recent multiscale composite analysis examples involving (i) creep of a woven ceramic matrix composite (CMC), (ii) damage/failure of a polymer matrix composite (PMC) T-stiffened panel, and (iii) damage/failure of notched PMC laminated plates.

The authors are, perhaps more than anyone, indebted to Professor Jacob Aboudi for his technical excellence, creativity, graciousness, and overwhelming generosity. Our success is in large measure a result of years of collaboration with him. Jacob – thank you for your professionalism, friendship, council, and most of all your example of humility and class.
