8.1 Future Research
This report developed nonlinear theories for modeling of piezoelectric integrated
thin-walled smart structures. Geometrically nonlinear models include von Kármán
type nonlinear, moderate rotation nonlinear, fully geometrically nonlinear with moderate rotations and large rotations. Materially nonlinear considers electroelastic nonlinearity, which permits piezo materials being under strong electric field. Even though
the most important modeling techniques have been discussed in this report, there are
some new theories have to develop for newly advanced smart structures, e.g. magnetoelectro-elastic structures, viscoelastic smart structures. The future research interests
in this field may include:
1. With the development of new materials and structures, these structures integrated
not only with electric and elastic fields, but also with other physical fields, e.g. thermal, magnetic, fluid fields. Multi-physics coupled modeling techniques are quit
needed for numerical simulations of the advanced smart structures.
2. Geometrically and electroelastic materially nonlinear has already considered in
this report. However, for materially nonlinear effects, only electroelastic coupled
nonlinear is included, many other material nonlinearities should be included in
the model, for example hyperelastic nonlinear, electro-magneto-thermo-elastic
coupled nonlinear, etc.
3. Nonlinearities and multi-physics coupled simulations leads to high computational
consumption. High efficiency plate/shell elements based on various through thickness hypotheses should be developed.
4. New plate/shell theories should be developed and proposed for structures with
large differences on each lamina, like viscoelastic piezo laminated structure.
