materials into morphing structures. This Undergraduate Thesis Project aims the
determination of the smart materials capabilities to control beam deformations.
Different analyses are performed to a sandwich beam with piezoelectric materials
embedded within it in order to quantify the contribution to the beam de
ections
of the response of the piezoelectric actuators to the presence of an electric field in
the environment. The temperature difference existing in the beam surroundings
is also studied to analyze if it affects the piezoelectric capability to modify the
beam response. The analytic model for predicting beam deformations, accounting
with the contribution of the piezoelectric actuator is based on the Kirchhoff beam
model, combined with the Classical Laminated Plate Theory for composite laminae
behavior description applied to sandwich beams.[+][-]
