“…Using the Sequential Linear Programming (SLP) method, the material topology is realized [7,8]. The design variables describe the allocation of piezoelectric material and polarization degrees at each finite element unit, and this can be applied to the design of sensors, actuators, and energy harvesters [9,10]. The geometric design freedom and multi-material parallelism of 3D printing make it possible to manufacture topology-optimized flexible mechanisms.…”

Topological optimization can realize the optimization of the mass distribution in the whole objective domain. Compared with morphology and size optimization, it has a higher degree of freedom. In this work, the three-dimensional topological optimization based on piezoelectric materials was discussed. Using the Optimality Criteria, topology optimization was applied to the cantilever piezoelectric transducer. The structure optimization was realized with the voltage and stiffness as the multi-objective function. The corresponding codes are given to show the process of optimization. With 70% of the origin volume, the bi-objective optimization increases the global stiffness by 50.9% and the voltage by 30%. As the iteration process shows, the results of bi-objective optimization prove the value of additive mass at the bottom of the cantilever. This lays the foundation for future piezoelectric transducer structural optimization. Using only stiffness as the objective, the final objective increases inconspicuously. Bi-objective optimization shows its superiority. There are quite a few papers that research the combination of stiffness and voltage, and research which studies three-dimensionality is a point of innovation. Furthermore, this is also the first time a piezoelectric topology code has been shared.

A novel smart hybrid-Trefftz finite element (HTFE) has been developed for the analysis of smart laminated composite plates. The substrates of the smart plates are symmetric and antisymmetric cross-ply plates. The derivation of this HTFE is devoid of the complicated task of finding the particular solutions of simultaneous governing partial differential equations. The Trefftz functions are constructed from the finite number of free-field exact solutions of the homogeneous simultaneous governing partial differential equations of the element domain in a straightforward manner without transforming them into a single governing equation. The HTFE is validated with the exact solutions of the smart composite plates. It is observed that this HTFE is an efficient finite element and can be utilized for the analysis of active control of smart composite structures.

The concept of using piezoelectric materials with structural elements is to monitor the behavior of the structure when it is subjected to a load. This paper describes a kind of self repairing structures by integrating the piezoelectric patch with laminated composite plate. The coupled character of mechanical and electrical behavior of piezoelectric material will be used to sense the deformation in the material and actuate it to resist the deformation when subjected to a load. The fatigue behavior of the laminated composite plate is studied for the cyclic bending load by experiment. Mathematical simulation is carried out using finite element method. The test specimen is prepared from a glass/epoxy laminated composite plate. The laminate is constructed as cross-ply with 50:50 fiber/matrix. The alternating stresses are derived from the tensile and three point flexure tests. The fatigue behavior is studied for the constant amplitude displacement at three different stress levels. Based on the fatigue characteristics observed from the experiments, the laminate without and with piezoelectric patch are simulated using finite element method. The simulation results for laminated composite plate with piezoelectric patch has shown a considerable increase in the fatigue life cycles. CITATION: M. Sundaravadivel and R. Dhanaraj. 2010.
