Comparison of Reduction Methods for Finite Element Geometrically Nonlinear Beam Structures

The aim of this contribution is to present numerical comparisons of model-order reduction methods for geometrically nonlinear structures in the general framework of finite element (FE) procedures. Three different methods are compared: the implicit condensation and expansion (ICE), the quadratic mani...
