Evaluation of linear and quadratic modal analysis for a partitioned FSI solver

In this paper, linear and quadratic modal approximations of elastodynamic solid deformation in FSI problems are considered. Firstly, the theory of quadratic exten- sion of modal analysis presented in [1] is laid out. The quadratic and linear approximations are then benchmarked against full FEM analysis in various test cases. These are chosen to be representative of flutter considerations in the aerospace field. The quadratic ap- proximation is shown to produce a markedly better prediciton of solid deformation for small to medium deflections
