Smart materials are responsive materials that possess adaptive capabilities to changes in external stimuli. Electrostrictive polymers, piezoelectric materials, electro-rheological and magneto-rheological fluids, shape memory alloys and magneto-strictive materials fall within this category. The field of smart materials has advanced rapidly due to an increasing awareness of their capabilities and numerous potential applications in various ectors, namely aerospace, aeronautic, industrial, automotive, biomedical, and micro and nano-systems. The smart materials are known to exhibit various degrees of hysteresis and nonlinear dynamics, which poses considerable challenges for the controller design. The accurate and efficient quantification of these effects form the primary requirements for controller design in order to exploit full capabilities of various materials. The primary purpose of this special session is to document the current state-of-the-art works on characterization of hysteresis effects, modeling techniques and corresponding control methods for smart materials through a collection of original and high-quality papers.

Topics include, but are not limited to:

• Modeling for smart material based actuators (e.g. Dielectric Elastomers, piezo-electrics, shape memory alloys, magneto-rheological fluids, etc.)
• Characterization of nonlinearities including hysteresis of different smart materials
• Rate dependence of hysteresis – characterization and modeling techniques
• Nonlinear control of smart material based actuators and sensors
• Industrial applications of systems involving smart materials
• Smart structures, active vibration control, active/passive damping, etc.
