Guaranteed Stability

In light of past research in this field, this paper intends to discuss some innovative approaches in vibration control of smart structures, particularly in the case of structures with embedded piezoelectric materials. In this work, we review the principal problems in mechanical engineering that the structural control engineer has to address when designing robust control laws: structural modeling techniques, uncertainty modeling, and robustness validation under stochastic excitation. Control laws are desirable for systems where guaranteed stability or performance is required despite the presence of multiple sources of uncertainty.

Pros And Cons

In this paper two distinct methods, an impedance method and a “conventional” method, for modeling the dynamic interaction between the piezoelectric actuators/sensors and the substructures are summarized. It is demonstrated that both methods yield equivalent models for the beam with piezoceramic actuation. The pros and cons of each technique are discussed.

Plates And Shells

Piezoelectric materials embedded into plates and shells make the structures being capable of sensing and actuation, usually called smart structures, which are frequently used for shape and vibration control, noise control, health monitoring, and energy harvesting. To give a precise prediction of static and dynamic behavior of smart structures, the linear/nonlinear multi-physics coupled modeling technique is of great importance. The article attempts to present the available research on modeling of piezoelectric integrated plates and shells, including (1) through thickness hypotheses for beams, plates, and shells; (2) geometrically nonlinear theories for plates and shells; (3) electroelastic material linear/nonlinear modeling; (4) multi-physics coupled modeling; and (5) modeling of advanced piezo-fiber composite bonded structures.

Piezoelectric Behavior

The development and application of smart structures and smart composite materials require efficient numerical tools to analyze the thermo-piezoelectric behavior and stress state. In this paper, finite element (FE) techniques are suggested for three-dimensional coupled thermo-electro-mechanical analyses. The actual thermo-piezoelectric responses of smart structures subjected to thermal loadings can be determined by adopting a procedure TPESAP. The detailed implementation is presented with emphasis on the integration with software ABAQUS. A benchmark problem is discussed afterwards.

Delamination Damage

The concept of damage detection using sensors in composite panels is of growing interest, due to the reduction in maintenance activity and increasing of the aircraft safety. Piezoelectric materials have been widely used to build a variety of transducers for activating and receiving Lamb waves which are used for delamination/damage detection. The aim of this paper is to use smart structures for detecting and locating damage in composite panels, by using piezoelectric patches as both sensors and actuators.
