Fabricating optical fibre-top cantilevers for temperature sensing [PDF]

open access: yes, 2014
In this paper, we propose techniques to fabricate micro-cantilevers onto the end of standard single mode optical fibres using a combination of picosecond laser machining and focused ion beam milling techniques and demonstrate their use as temperature ...

Cantilever micro-rheometer for the dcharacterization of sugar solutions [PDF]

open access: yes, 2008
The volume required for the rheological characterization of fluids can be minimized by using micromechanical cantilevers as viscosity sensors. Here, a simple measurement tool for the characterization of sugar solutions is proposed. The sensor consists of

Dynamic cantilever magnetometry of individual ferromagnetic nanotubes [PDF]

open access: yes, 2014
In this thesis, we focus on a particular aspect of nanotechnology, namely the understanding of magnetic states in nanometer-scale objects. Describing microscopic magnetization states and reversal is particularly important for the development of magnetic ...

Active Vibration Control of Cantilever Beam by Using Optimal LQR Controller

open access: yesJournal of Engineering, 2018
Many of mechanical systems are exposed to undesired vibrations, so designing an active vibration control (AVC) system is important in engineering decisions to reduce this vibration. Smart structure technology is used for vibration reduction.

A new scanning force microscope for temperature-controlled static and dynamic friction measurements, using an extended normal and lateral working range with high spatial resolution [PDF]

open access: yes, 2013
In this work, a new and improved SFM is presented. This SFM can measure many variables such as the individual dynamic and active temperature regulation of the sample and the cantilever, miscellaneous friction modes, x-, y-, z- linearization and an ...

Development of an opening-tearing mode fracture system for composite materials

open access: yesEPJ Web of Conferences, 2010
In this paper the mixed-mode I/III prestressed split-cantilever beam fracture specimen [1,2] is developed, which combines the mode-III modified split-cantilever beam [1] and the well-known double-cantilever beam [3] specimens using a special rig.

Analytical and numerical investigation of free vibration for stepped beam with different materials

open access: yesOpen Engineering, 2022
This work describes the application of classical Rayleigh method (CRM), modified Rayleigh method (MRM), and ANSYS finite element method (FEM) to calculate the natural frequency of non-homogenous cantilever beam.
