Isochronous Beams by an Inclined Roller Support
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The paper addresses the problem of isochronous beams, namely those that oscillate with a frequency that is independent of the amplitude also in the nonlinear regime. The mechanism adopted to obtain this goal is that of ...
A Global Dynamics Perspective for System Safety From Macro to Nanomechanics: Analysis, Control, and Design Engineering
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The achievements occurred in nonlinear dynamics over the last 30 years entail a substantial change of perspective when dealing with vibration problems, since they are now deemed ready to meaningfully affect the analysis, ...
On the Dynamics of a Biomimetic Model of a Sympodial Tree: From Bifurcations Diagrams and 6D Basins of Attraction to Dynamical Integrity and Robustness
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work is concerned with a mechanical model of a sympodial tree with first-level branches, which has been shown to exhibit certain properties potentially suitable for biomimetic applications. To investigate these potential ...
Boosting the Model Discovery of Hybrid Dynamical Systems in an Informed Sparse Regression Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We present an efficient data-driven sparse identification of dynamical systems. The work aims at reconstructing the different sets of governing equations and identifying discontinuity surfaces in hybrid systems when the ...
Nonlinear Vibrations of a Composite Beam in Large Displacements: Analytical, Numerical, and Experimental Approaches
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper investigates the nonlinear dynamic behavior of a cantilever beam made of composite material without and with lumped mass fixed along its length. The analysis compares the results coming from analytical and ...
Attractors' Analysis and Bifurcation Diagrams for an Impacting Inverted Pendulum in the Presence of a Two-Terms Harmonic Excitation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this work, we examine the nonlinear dynamics of an inverted pendulum between lateral rebounding barriers. We continue the numerical investigation started in (Demeio et al., 2006, “Response Scenario and Non-Smooth Features ...
Modeling and Analysis of an Electrically Actuated Microbeam Based on Nonclassical Beam Theory
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work investigates the mechanical behavior of a clampedclamped microbeam modeled within the framework of the straingradient elasticity theory. The governing equation of motion gives proper account of both the effect ...
Non-Smooth Dynamics of Tapping Mode Atomic Force Microscopy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study examines the nonlinear dynamics in tapping-mode atomic force microscopy (AFM) with tip-surface interactions that include van der Waals and Derjaguin-Müller-Toporov contact forces. We investigate the periodic ...
Sparse Metapiles for Shear Wave Attenuation in Half-Spaces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We show that shear waves traveling toward the surface of a half-space medium can be attenuated via buried one-dimensional arrays of resonators—here called metapiles—arranged according to sparse patterns around a site to ...
Special Issue: Dynamics of Systems With Impacts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In single degreeoffreedom (DOF) oscillators, impacts can occur with a barrier while in a system with multiple DOF, one can additionally observe impacts among interacting bodies. On the one hand, impacts are intrinsic for ...
