First, an efficient and accurate finite element model for smart composite beams is presented.
The developed model is based on layerwise theory and includes the electromechanical coupling effects. Then,
an efficient design optimization algorithm is developed which combines the layerwise finite element analysis
model for the smart laminated beam, sensitivity analysis based on analytical gradients and sequential quadratic
programming (SQP). Optimal size/location of sensors/actuators is determined for dynamic displacement measurement
purposes and for vibration control applications. For static and eigenvalue problems, the objective is
to minimize the mass of the beam under various constraints including interlaminar stresses, displacements, and
frequencies. For transient vibration problems, the objective is the minimization of the actuation control effort
to suppress the vibration in a controlled manner. Illustrative examples are provided to validate the formulation
and to demonstrate the capabilities of the present methodology. |
