Buckling temperature prediction of a functionally graded piezoelectric (FGP) sandwich plate with lightweight core is studied in the present work. The composite made three layers. upper and lower layers are two different materials so that electrical mechanical properties smoothly varied through thickness based on power law distribution. Whereas, considered as hexagonal honeycomb structure or por...

Piezoelectric actuators (PEAs) have been widely used in micro- and nanopositioning applications due to their fine resolution, rapid responses, and large actuating forces. However, a major deficiency of PEAs is that their accuracy is seriously limited by hysteresis. This paper presents adaptive model predictive control technique for reducing hysteresis in PEAs based on autoregressive exogenous m...

An isogeometric analysis (IGA) method is proposed for investigating the active shape and vibration control of functionally graded plates (FGPs) with surface-bonded piezoelectric materials in a thermal environment. A simple first-order shear deformation theory (S-FSDT) four variables used to describe displacement field plates. To ensure investigation smart structure environment closer actual sit...

The aim of this paper is to propose a complete normalized study of a diaphragm's behavior under classical excitation encountered in microsystem: pneumatic, electrostatic, piezoelectric and magnetic. The principle of modeling is widely described in order to be easily applied to other structure. First, a traditional analytical solution is recalled for the diaphragm's deflection based on energy mi...

An actuator is a device that converts input energy into mechanical energy. According to various types of input energy, various actuators have been advanced. Displacement in the electromagnetic, hydraulic and pneumatic actuators achieve by moving a piston via electromagnetic force or pressure, however the piezoelectric actuator (piezoceramic plates) displace directly. Therefore, accuracy and spe...

This article deals with the analysis of active constrained layer damping (ACLD) of smart multiferroic or magnetoelectro-elastic doubly curved shells. The kinematics of deformations of the multiferroic doubly curved shell is described by a layer-wise shear deformation theory. A three-dimensional finite element model of multiferroic shells has been developed taking into account the electro-elasti...
