Damping Estimation of Friction Systems in Random Vibrations,owed that two of the methods estimate efficiently the equivalent linear damping, however, the equivalent linear damping seems to depend on the definition of the equivalence. Nonetheless, it seems that the variation of the equivalent linear damping estimates based on the three aforementioned methods

System Identification of Jointed Structures: Nonlinear Modal Testing Vs. State-Space Model Identifiure with bolted joints. The quality of the extracted modal and state-space models, respectively, is assessed by comparing model-based predictions of the forced vibration response to reference measurements.

Interface Reduction on Hurty/Craig-Bampton Substructures with Frictionless Contact,resonant frequencies vary as a function of the response amplitude. Finite element analysis is commonly used to study the physics of such problems, particularly when examining the local behavior at the interfaces. These high fidelity, nonlinear models are computationally expensive to run with time-st

Direct Detection of Nonlinear Modal Interactions and Model Updating Using Measured Time Series,is motivated by the desire to quantify the degree of nonlinearity of a system, with the ultimate goal of updating a finite-element or other mathematical model to capture the nonlinear effects accurately. Our method relies on the proper orthogonal decomposition to extract proper orthogonal mode shape
