Abstract

Viscoelastic torsion under piezoelectric control - analytical and massively parallel computational simulations and performance evaluations C. E. Beldica, H. Hilton & S. Koric Aeronautical and Astronautical Engineering Department, National Center for Supercomputing Applications and Center for Simulation of Advanced Rockets, University of Illinois at Urbana-Champaign, USA 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
