Predicting S4 Beam Joint Nonlinearity Using Quasi-Static Modal Analysis, and preload values needed to reach agreement with experimental measurements. Additionally, the shape of the actual contact interfaces is measured using a profilometer and fed into the model to quantify the effect of slight curvature in the contact.

Experimental Nonlinear Dynamics of a Post-buckled Composite Laminate Plate,is measured with the 3D dynamic digital image correlation (DIC) technique combined with a laser vibrometer. The results show single-well and coexisting responses for the four stable equilibria along with chaotic snap through between equilibria. The experimental results of the pre-buckled plate modal

Reinforcement Learning for Active Damping of Harmonically Excited Pendulum with Highly Nonlinear AcCO reinforcement learning algorithm was used to optimize a control policy for the electromagnet with the objective of minimizing the distance between the end of the pendulum and the downward position. After 16 s of interaction with the experimental system, the resulting learned policy was able to su

Investigation of Nonlinear Dynamic Phenomena Applying Real-Time Hybrid Simulation,prises of standard hardware components used in modal testing including electrodynamic shakers, force, displacement and acceleration sensors and furthermore a real-time processing unit with feedback control for proper system coupling. For periodic forcing, the efficiency of the proposed method is dem

Experimental and Numerical Aeroelastic Analysis of Airfoil-Aileron System with Nonlinear Energy Sinnd Reynolds-Averaged Navier Stokes (high fidelity) methods. The numerical methods present good agreement, within the limits of each approach, and correspond with the experimental data. Using the NES, a gain of flutter speed is reached compared to the linear flap restoring force configuration.

On the Modal Surrogacy of Joint Parameter Estimates in Bolted Joints,d joint interface modeling approaches have been tackled, the current investigation studies the so-called “modal surrogacy” of a structural system. The investigation serves to understand the sufficiency of modeling the nonlinear behavior in lower modes to make high-modal nonlinear predictions. The Br
