Piezoelectric Creep Divergence Control Of Flexible Viscoelastic Lifting Surfaces - Analytic And Computational Simulations
Analytical and numerical solutions are presented for viscoelastic lifting surfaces with piezoelectric control devices. Computational protocols in terms of spatial finite elements and temporal finite differences are formulated. ANSYS is used for mesh generation and numerical solutions are carried out in ABAQUS. Because of lack of provisions in ABAQUS for displacement dependent forces (lift), additional iterative subroutines were written and incorporated.
