Experimental Characterization of a New Benchmark Structure for Prediction of Damping Nonlinearity,nd these joints lead to large uncertainties in the structural stiffness, damping and can even introduce nonlinearity. Even with the best available simulation tools, it is still difficult to predict the effective stiffness and damping of bolted interfaces, and so these parameters are often assumed an

Nonlinear System Identification for Joints Including Modal Interactions, is currently necessary to identify models for these non-linear structures experimentally. One approach is to assume that the modes are decoupled and to fit a non-linear model to match the response for each mode in isolation. This modal approach has found to be suitable for systems with very weak no

System Identification to Estimate the Nonlinear Modes of a Gong, the authors have used force appropriation to measure NNMs, but this is time consuming, generally requiring hand tuning of both the frequency in question and the strength of its harmonics. This paper explores the use of system identification, using a small set of broadband response data, to estimate

An Enhanced Static Reduction Algorithm for Predictive Modeling of Bolted Joints,an presumably be modeled in commercial FE codes, even quasi-static analysis is extremely expensive due to the level of detail required to capture micro-slip. This work explores the application of a new static reduction method to reduce the computation costs associated with analyzing built-up structu

Operational Modal Analysis Based Stress Estimation in Friction Systems,techniques are based on the assumption that the system is linear. However, this is not always the case since nonlinear elements often violate this assumption. In this paper, the precision of estimating the strain response of a nonlinear system is investigated using the operational response of numeri
