主要内容：Synergistic integration of modern "smart" materials, structures, machines, sensors, actuators, and control electronics can transform conventional passive structures and machines to active, multi-functional and adaptive "smart" structronic (structure + electronic) systems with inherent self-sensing, diagnosis, control, healing and/or repair capabilities. Starting with an overview of smart structures and advanced distributed parameter systems (DPSs) (e.g., nozzles, rockets, blades, mirrors, reflectors, antennas, solar panels/collectors, etc.), this report focuses on 1) multi-field coupling of photo-magneto-thermoelectromechanical responses of distributed photo-magneto and piezoelectric-thermoelastic structronic shell systems and 2) distributed sensing, energy generation and control of structronic shell systems. The first topic focuses on distributed actuation and control using various smart materials. Actuation forces and moments defined by piezoelectric, electrostrictive, magnetostrictive and photostrictive actuators are discussed. Two design principles, i.e., the segmentation technique and the shaping technique, are proposed. Simplifications of the generic theories to engineering structures are presented. The second topic focuses on distributed sensing, energy conversion and control of structroinc shells, i.e., elastic shells coupled with distributed sensing and control layers. Microscopic distributed energies, membrane control forces and control moments are evaluated. Practical applications are also discussed.
