A sub-structuring approach for model reduction of frictionally clamped thin-walled structures
Patrick Hippold, Johann Gross, Malte Krack
Thin-walled structures clamped by friction joints, such as aircraft skin panels are exposed to bending-stretching coupling and frictional contact. We propose an original sub-struct…

An iteration-free approach to excitation harmonization
Patrick Hippold, Gleb Kleyman, Lukas Woiwode +6
Sinusoidal excitation is particularly popular for testing structures in the nonlinear regime. Due to the nonlinear behavior and the inevitable feedback of the structure on the exci…

Robust and fast backbone tracking via phase-locked loops
Patrick Hippold, Maren Scheel, Ludovic Renson +1
Phase-locked loops are commonly used for shaker-based backbone tracking of nonlinear structures. The state of the art is to tune the control parameters by trial and error. In the p…
