Nonlinear Modal Substructuring of Geometrically Nonlinear Finite Element Models

  title={Nonlinear Modal Substructuring of Geometrically Nonlinear Finite Element Models},
  author={Robert J. Kuether},
In the past few decades reduced order modeling (ROM) strategies have been developed to create low order modal models of geometrically nonlinear structures from detailed finite element models built in commercial software packages. These models are capable of accurately predicting responses at a dramatically reduced computational cost, but it is often not straightforward to determine which modes must be included in the reduction basis. Furthermore, much of the upfront cost associated with these…

The nonlinear reduced order models of large scale finite element models are used to approximate the nonlinear normal modes (NNMs) of detailed structures with geometric nonlinearity distributed throughout all of its elements to give a load-independent metric that may provide confidence in the accuracy of the ROM while avoiding the excessive cost of computing the complete NNM of the full order model.
