Topology Optimization of Constrained Layer Damping on Plates Using Method of Moving Asymptote (MMA) Approach

open access: yesShock and Vibration, 2011
Damping treatments have been extensively used as a powerful means to damp out structural resonant vibrations. Usually, damping materials are fully covered on the surface of plates.

Analytical model of high-frequency energy flow response for a beam with free layer damping

open access: yesAdvances in Mechanical Engineering, 2020
Energy flow analysis (EFA) is developed to predict the vibrational energy density of beam structures with both full free layer damping (FFLD) and partial free layer damping (PFLD) treatments in the high frequency range. Both equivalent flexural stiffness

Electromechanical coupling modeling and analysis of piezoelectric damping laminated structures based on zig-zag hypothesis

open access: yesXibei Gongye Daxue Xuebao, 2022
Based on the zig-zag theory and Hamiltonian principle, the electromechanical coupling dynamic finite element(FE) model of piezoelectric damping laminated structure is established, the natural frequency and loss factor of the structure is accurately ...

Viscothermal Damping in Thin Gas or Fluid Layers [PDF]

open access: yesAdaptive Structures and Material Systems, 1999
Abstract This paper deals with viscothermal wave propagation, including acousto-elastic interaction. For wave propagation in thin gas or fluid layers, the effects of viscosity and thermal conductivity have to be accounted for. These effects can introduce a significant dissipation of energy.

A study of joint damping in metal plates [PDF]

open access: yes, 2009
For satellite applications the determination of the correct dynamic behaviour and in particular the structural damping is important to assess the vibration environment for the spacecraft subsystems and ultimately their capability to withstand the launch ...

Monitoring the effects of impact damages on modal parameters in carbon fiber entangled sandwich beams [PDF]

open access: yes, 2009
The aim is to study the impact toughness of two types of entangled sandwich materials (heavy and light) with the help of vibration testing. A simple case of symmetrical impacts is studied in this article as no literature is available regarding impact ...

Numerical test of the damping time of layer-by-layer growth on stochastic models [PDF]

open access: yesPhysical Review E, 1999
We perform Monte Carlo simulations on stochastic models such as the Wolf-Villain (WV) model and the Family model in a modified version to measure mean separation $\ell$ between islands in submonolayer regime and damping time $\tilde t$ of layer-by-layer growth oscillations on one dimension.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Integrating damping and non-linearities in a vibration design process [PDF]

open access: yes, 2013
Classical vibration design uses modes and transfer functions generated with the superposition principle to allow the verification of design objectives.
