Effective computational methods for the solution of ferroelectroelastic problems under complex loading

Enhanced numerical methods for the solution of three-dimensional nonlinear electromechanically coupled boundary value problems are considered. A vector potential finite element formulation with return mapping algorithm and consistent tangent operator is developed. The accuracy and robustness of the algorithms are assessed with the help of numerical examples concerning a ferroelectroelastic analysis of structures under complex multiaxial non-proportional loading.
