Abstract:

The dynamic mode atomic force microscope (AFM) is a versatile tool that uses a resonantly excited micro-cantilever probe to obtain a sample’s topography and to characterize its material properties. While a number of useful techniques have been developed for interacting with the sample, conventional AFM probes and AFM systems do not facilitate their effective implementation. This thesis investigates the design of specialized AFM probes and the development of a novel probing system that improves the speed of imaging and enhances the sensitivity to material properties in dynamic mode AFM.

Abstract:

Abstract When a laminated sandwich beam consisting of alternating elastic and viscoelastic layers bends in the plane normal to its plane of lamination, the relatively compliant viscoelastic layers are sheared between the adjoining elastic layers and energy is dissipated. This mechanism, known as constrained-layer or shear damping, is a proven method for damping flexural vibration, but only in the plane normal to the plane of lamination. For vibration parallel to the plane of lamination, the elastic layers need not deflect together, and the viscoelastic layers are sheared when adjoining elastic

Abstract:

Flexure pivot based oscillators can advantageously replace the hairspring and balance wheel, the time base used in mechanical watches, by drastically reducing friction. However, flexure pivots have drawbacks including gravity sensitivity and restoring torque nonlinearity. In previous work, we introduced a novel gravity insensitive flexure pivot (GIFP) to solve the problem of gravity sensitivty, but no analytical formulation for the restoring torque nonlinearity was found. In this paper, we use numerical simulation to find an empirical expression for restoring torque nonlinearity. We use this e

Abstract:

The three-dimensional motions of a clamped-free, inextensible beam subject to lateral harmonic excitation are investigated in this paper. Special attention is given to the nonlinear oscillations of beams with low torsional stiffness and its influence on the bifurcations and instabilities of the structure, a problem not tackled in the previous literature on this subject. For this, the nonlinear integro-differential equations describing the flexural-flexural-torsional couplings of the beam are used, together with the Galerkin method, to obtain a set of discretized equations of motion, which are

Abstract:

Abstract The dynamic analysis of parametrically excited rotors is a research field of great interest and practical importance, since instability and resonant behavior can cause issues ranging from anomalous noise and wear to catastrophic failures. This study is focused on the effects of unbalance on a parametrically excited rotor operating in the asymptotically stable domain, a research topic which in the scientific literature has not been investigated. Rotor unbalance causes an additional harmonic load acting on flexural deflection, influencing the frequency response together with the paramet

Abstract:

In this paper, we study the fluid-structure interaction problem of the harmonic oscillations of a flanged lamina in a quiescent, Newtonian, viscous fluid. Here, the flanges are introduced to elicit specific vortex-structure interactions, with the ultimate goal of modulating the nonlinear hydrodynamic damping experienced by the oscillating structure. The hydrodynamic forcing, incorporating added mass and hydrodynamic damping effects, is evaluated through boundary element method and computational fluid dynamics simulations. This allows to identify a model for the hydrodynamic forces in the form

Abstract:

Continuous current action on risers develops vortices. These vortices cause risers to respond in a dynamic manner, leading to relatively large oscillations in the flexural and circumferential stresses. Vortex-induced vibration (VIV) and the resulting changes in the level of stresses in a riser could therefore cause detrimental fatigue induced problems, ranging from leakage to catastrophic failure of the riser. As a result, the VIV induced fatigue has always been a critical parameter in the design of risers, particularly when considering risers in deep waters. An experimental investigation into

Abstract:

Abstract This work analyses the mooring and power cable dynamics in large-scale experimental tests carried out in the wave-current-tsunami flume (COCOTSU) facility at IHCantabria. The analysis is based on scaled elastic string models for a single chain-nylon mooring line and the dynamic cable of a 15MW floating offshore wind turbine (FOWT) supported by a concrete semi-submersible platform (ActiveFloat) in Gran Canaria Island (Spain). Both scaled concepts in the 100 m deep site are developed within the framework of the project COREWIND. All the test campaign is planned to be fully monitored; he
