Abstract
The effects of controlling torsional creep deformations of viscoelastic bars through
applications of piezoelectric devices is investigated and solved by finite element
methods. It is shown that delamination failure probabilities can be retarded by the
proper imposition of voltages. Computational performance evaluation studies for
CPU times and speed ups are undertaken for distinct number of processors and eval-
uated.
1 Introduction
Piezoelectric effects are of increasing importance in the control and sensing of struc-
tural element deflections. Elastic piezoelectric theory has been extensively devel-
oped
