Nonlinear Finite Element Modelling Of Composite
Structures With Integrated Piezoelectric Layers
Author(s)
S. Lentzen & R. Schmidt
Abstract
A geometrically nonlinear composite shell element with integrated piezoelectric
layers is presented. Three translational and two rotational nodal degrees of freedom
are used for the first-order transverse shear approximation. The finite element
is tested on a number of static problems using the piezoelectric layers as actuators
as well as sensors. The numerical approximations to these static problems are
obtained using the total Lagrangian formulation for the moderate rotation shell
theory. The significance of a geometrically nonlinear formulation in order to predict
the sensor properties is shown.
Keywords: geometrical nonlinearity, piezoelectricity, actuators, sensors.
