Available in PDF, EPUB and Kindle. Book excerpt: This book presents a compilation of lectures delivered at the São Paulo School of Advanced Sciences on Nonlinear Dynamics, categorized into four groups: parametric resonance, nonlinear modal analysis and model reduction, synchronization, and strongly nonlinear dynamics. Interwoven seamlessly, these groups cover a wide range of topics, from fundamental concepts to practical applications, catering to both introductory and advanced readers. The first group, consisting of chapters 1 and 2, serves as an introduction to the theory of parametric resonance and the dynamics of parametrically excited slender structures. Chapters 3, 4, and 5 form the second group, offering insights into normal forms, nonlinear normal modes, and nonlinear system identification. Chapters 6 and 7 delve into asynchronous modes of structural vibration and master-slave topologies for time signal distribution within synchronous systems, respectively, representing the third group. Finally, the last four chapters tackle the fourth group, exploring nonlinear dynamics of variable mass oscillators, advanced analytical methods for strong nonlinear vibration problems, chaos theory, and dynamic integrity from the perspectives of safety and design. This book harmoniously combines theoretical depth and practical relevance to provide a comprehensive understanding of nonlinear dynamics.

Download or read book Model Correlation and Updating of Geometrically Nonlinear Structural Models Using Nonlinear Normal Modes and the Multi harmonic Balance Method written by Christopher Ian Van Damme and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Future generations of advanced spacecraft and aircraft will have a digital twin, or a model that is used to predict life and that is updated as the vehicle ages. A key component of the digital twin concept is the structural dynamics surrogate model that is used to simulate the response of structural components to the loads that the vehicle experiences. The structural surrogate will be used to predict responses, stress and ultimately the estimated life of the vehicle. The most common approach for modeling structures in the aerospace industry is the Finite Element (FE) method, which can accurately simulate the response of the structural components due to various loading conditions. Many of these advanced vehicles will also be operating in extreme environments where certain components may behave nonlinearly such as the large deformations of thin panels. As a result, to use an FE model to simulate the response would be extremely expensive. To circumvent the use of FE models to compute the nonlinear response of structures, methods have been sought to create reduced order models (ROM)s, which capture the essential characteristics of the parent FE model but at a greatly reduced computational cost. One disadvantage of ROMs is that it tends to be more difficult to ensure that they are accurate. Regardless of the numerical modeling approach used they are unlikely to exactly represent the physical structure. As a result, model correlation and updating procedures are required to ensure they are accurate representations of the real hardware. Unfortunately, linear model correlation and validation techniques that are commonly used in the aerospace industry are no longer valid in the nonlinear response regime so a new set of tools is required to validate nonlinear models. Both the nonlinear FE models and nonlinear ROMs can be highly sensitive to boundary conditions, imperfections and pre-stresses which are difficult to account for in the initial model and thus model updating is required. Furthermore, as the structure ages, changes to the structure can occur and must be properly accounted for to ensure life predictions remain accurate. The primary contribution of this work is the development of a model correlation and updating procedure applied to both FE models and ROMs based upon Nonlinear Normal Modes (NNMs) computed using the Multi-Harmonic Balance method. The NNMs serve as a strong metric to correlate the numerical models, because they represent the dynamics of the nonlinear system over a range of amplitudes and they are independent of the loading applied to the system. NNMs can be extracted from experiments so that numerical models can be correlated and validated with test data. This work presents a novel method of computing analytical gradients of the NNMs' solutions with respect to system parameters greatly accelerating the model updating procedure. The procedure is applied to both FE models and ROMs for several experimental systems demonstrating the capabilities of the model updating procedure for the two representations of geometrically nonlinear systems.

Book excerpt: This book deals with the various aspects of stochastic dynamics, the resolution of large mechanical systems, and inverse problems. It integrates the most recent ideas from research and industry in the field of stochastic dynamics and optimization in structural mechanics over 11 chapters. These chapters provide an update on the various tools for dealing with uncertainties, stochastic dynamics, reliability and optimization of systems. The optimization–reliability coupling in structures dynamics is approached in order to take into account the uncertainties in the modeling and the resolution of the problems encountered. Accompanied by detailed examples of uncertainties, optimization, reliability, and model reduction, this book presents the newest design tools. It is intended for students and engineers and is a valuable support for practicing engineers and teacher-researchers.

Available in PDF, EPUB and Kindle. Book excerpt: This book is dedicated to the general study of fluid structure interaction with consideration of uncertainties. The fluid-structure interaction is the study of the behavior of a solid in contact with a fluid, the response can be strongly affected by the action of the fluid. These phenomena are common and are sometimes the cause of the operation of certain systems, or otherwise manifest malfunction. The vibrations affect the integrity of structures and must be predicted to prevent accelerated wear of the system by material fatigue or even its destruction when the vibrations exceed a certain threshold.
