Dr. Yapa Rajapakse

Dr. Yapa Rajapakse is the program manager of the Solid Mechanics Program at the Office of Naval Research (ONR). The current focus of this research program is the thermo-mechanical behavior of composite materials and composite sandwich structures in severe marine environments (in the presence of high levels of humidity, sea water, hydrostatic pressure, dynamic loading, and temperature extremes). Dr. Rajapakse completed his graduate studies at Stanford University, receiving a M.S. degree in Mathematics, and a Ph.D. degree in Applied Mechanics. His doctoral dissertation in the area of fracture mechanics was supervised by the late Prof. J.N . Goodier.

He has been elected a fellow of four technical societies: the American Society of Mechanical Engineers (ASME), the American Academy of Mechanics (AAM), the Society of Engineering Science (SES), and the American Society for Composites (ASC). He has served as president, vice-president, and member of the board of directors of the SES. He was also chairman of the Composites Committee, Applied Mechanics Division of ASME, and the Polymer Matrix Composites Division of ASC. Dr. Rajapakse has served on the editorial boards of several journals, including Composite Science and Technology, the Journal of Sandwich Structures and Materials, the Journal of Composite Materials, the Journal of Reinforced Plastics & Composites, Composites Part B, Engineering Fracture Mechanics, and the International Journal of Plasticity.

He has delivered numerous presentations at national/international conferences. He is the editor/co-editor of 32 books including the recently published “Dynamic Failure of Materials and Structures,” “Dynamic Failure of Composite and Sandwich Structures,” “Blast Mitigation: Experimental and Numerical Studies,” and “Durability of Composites in a Marine Environment.”

Blurb

This book primarily focuses on methodologies to enable marine structures to resist high velocity impact loadings. It is based on invited talks presented at the recent India–USA workshop on “Recent Advances in Blast Mitigation Strategies in Civil and Marine Composite Structures” The book comprises content from top researchers from India and the USA  and covers various aspects of the topic, including modeling and simulation, design aspects, experimentation and various challenges. These failure modes significantly reduce the structural integrity of the marine structures unless they are designed to resist such harsh loadings. Understanding the mechanics of these structures under harsh loadings is still an open area of research, and the behavior of these structures is not fully understood. The book highlights efforts to reduce the effects of blast loadings on marine composite structures. Intended for researchers/scientists and practicing engineers, the book focuses not only the design and analysis challenges of marine composite structures under such harsh loading conditions, but also provides new design guidelines.
