A shell finite element based on the Reissner/Mindlin first-order shear deformation theory and integrating a bi-dimensional phenomenological ferroelectric constitutive law for domain switching effects is proposed. An electric switching function is considered to indicate the onset of domain switching. Only one internal variable (the remanent polarization) is used in the model. An implicit integration technique based on the return-mapping algorithm is adopted. The shell element is implemented into the commercial finite element code Abaqus ® via the subroutine user element. Some linear (piezoelectric) and non-linear (ferroelectric) tests are considered to validate first, the element formulation and second, the implementation of the bi-dimensional ferroelectric model. It is shown by studying a complex example (the spiral actuator) that the Reissner/Mindlin kinematic hypothesis (no variation of the displacement across the thickness or no thickness variation) is not sufficient for some electromechanical applications for which the d33 effect is of major importance.

“…The main advantage of a tubular configuration is its good structural rigidity. Its applications include scanning probe microscopy (SPM), ultrasonic motors and some medical diagnostics and therapeutics devices [7][8][9][10][11]. It is also noted that processes facilitating miniaturization are essential for the development of future generations of electronic devices.…”

Piezoelectric ceramics actuators have been widely applied in industries and attracted huge attention in academic research during the last decades due to their many advantages such as good displacement resolution, good mechanical durability, high speed, large output force, low power consumption and wide bandwidth of frequencies [1][2][3][4][5]. However, Most of the piezoelectric devices can only be of a very simple shape or structure, such as a plate or a disk. This is largely due to the various difficulties in the fabrication technique. Due to the brittle nature of the piezo ceramics, machining them into complicated shapes remains as a challenge.However, the development of electrophoretic deposition (EPD) technique provides a choice for the fabrication of piezo devices of relatively complicated shapes and smaller dimensions [1,5,6]. EPD of piezo components is noted to be simple, cost effective, versatile and fast. EPD also allows for mass-production of devices, ranging in size from µm to cm in dimension. Technically, EPD is a colloidal process whereby ceramic bodies are shaped directly from a stable colloid powder suspension under a DC electric field. Generally, the colloid fabrication process consists of three stages: the formation of a charged suspension, the deposition of charged particles onto an electrode under a DC voltage and the final sintering of the deposited structure. Figure 9.1 shows the electrophoresis process schematically. A DC field causes the charged particles to move towards, and deposit on, the electrode of opposite charge. The depositing electrode reflects the shape of the ware required, and it is designed such that deposit release is facilitated.The investigation of electrophoretic deposition on piezoelectric or ferroelectric materials has existed for more than a decade [6]; however, the shape of the deposit
