Abstract :
Piezoelectric actuators are effectively used to
control the response of light weight structures in shape,
vibration and buckling. Optimization for the shape control
of piezoelectric beam is the recent challenge which
requires proper numerical technique to perform. The shape
control of a composite beam using surface-bounded
piezoelectric actuators has been investigated in the present
work. The mathematical model is developed using twonode
Timoshenko beam element coupling with the theory
of linear piezoelectricity. First-order shear deformation
theory is employed in the formulation to consider the effect
of shear. In the analysis, the effect of the actuators position
for different set of boundary conditions is investigated.
For different boundary conditions which include clampedfree-,
clamped–clamped- and simply supported beam,
optimisation of piezoelectric patch location is investigated.
Moreover, a genetic algorithm is adopted and implemented
to optimize the required voltage to maintain the desired
shape of the beam. This optimization technique is applied
to different cases of composite beams with varying the
boundary condition.
