Abstract

Nonlinear model order reduction based on subspace projection is driven by the exploitation of the structure of the nonlinearity or by analyzing data generated from the nonlinear model. In the proposed approach the one way coupling of bending and stretching in geometrically nonlinear beam or shell elements is considered for a nonlinear projectional framework that is able to consider inertia effects of both, bending and stretching motion. The method increases accuracy in comparison to static condensation approaches, however at the cost of higher computational efforts.
