Modelling and design of adaptive composite structures. (English)
[J] Comput. Methods Appl. Mech. Eng. 185, No.2-4, 325-346 (2000). ISSN 0045-7825

From the summary: The complexity in the design and fabrication of adaptive laminated composites has resulted in a need to develop reliable and refined models to study their material properties and mechanical behaviour. Here, we develop higher-order finite element formulations and an analytical closed-form solution to study the mechanics of adaptive composite structures with embedded and/or bonded piezoelectric actuators and sensors. Optimization of adaptive composite structures is also an important design aspect in order to maximize actuator performance. Thus two optimization schemes are considered in this study, where the design variables are layer thickness and actuator size and location. To demonstrate the validity of the proposed models, we present several illustrative examples.
