RISNonlinear Propagation of Wave-Packets on Fluid Interfaces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The method of multiple scales is used to derive two partial differential equations which describe the evolution of two-dimensional wave-packets on the interface of two semi-infinite, incompressible, ...
An Experimental Investigation of Multimode Responses in a Cantilever Beam
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimental investigation into the planar, multimode response of a cantilever metallic beam to a transverse harmonic excitation is presented. The cantilever beam was tested in both the ...
Nonlinear Vibrations of a Beam-Spring-Mass System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The nonlinear response of a simply supported beam with an attached spring-mass system to a primary resonance is investigated, taking into account the effects of beam midplane stretching and ...
High- to Low-Frequency Modal Interactions in a Cantilever Composite Plate
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We have shown through experiment a complicated dynamic behavior of a cantilever (90/30/–30/–30/30/90)s graphite-epoxy plate. The plate was base excited using a 2000-lb table shaker near its seventh ...
Dynamic Distribution of Displacement and Stress Considerations in the Ultrasonic Immersion Nondestructive Evaluation of Multilayered Plates
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A unified theoretical treatment is presented for the calculation of displacements and stresses within multilayered media subjected to incident ultrasonic waves. The wave is supposed to be incident ...
Acoustic Radiation From Multi-Span Baffled Panels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The objective of this study is to evaluate the acoustic radiation from a multi-span baffled panel having certain types of irregularities, including intermediate torsional springs and/or displaced ...
Flexural Wave Propagation in a Fluid-Loaded Elastic Plate With Periodically Varying Rigidity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The method of multiple scales is utilized to analyze the propagation of flexural waves in a fluid-loaded elastic plate with periodically varying rigidity. Subsonic modes are coupled under a ...
Bifurcation and Chaos in Externally Excited Circular Cylindrical Shells
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The nonlinear response of an infinitely long cylindrical shell to a primary excitation of one of its two orthogonal flexural modes is investigated. The method of multiple scales is used to ...
Damping Characteristics of Laminated Thick Plates
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We develop the analysis for the exact three-dimensional viscoelastic solution for simply supported, thick multilayered composite plate strips. Each layer is assumed to possess monoclinic or higher ...
On Nonlinear Modes of Continuous Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We use several methods to study the nonlinear modes of one-dimensional continuous systems with cubic inertia and geometric nonlinearities. Invariant manifold and perturbation methods applied to ...
