Effect of the deposition conditions of platinum electrodes on their performance as resistive heating elements

open access: yesMaterials Research, 2004
The performance of different platinum electrodes used as resistive heating elements was studied. Pt films having different thickness were deposited by RF magnetron sputtering at room temperature followed by post-deposition annealing at 700 ºC or made in ...

Approach for Calibrated Measurement of the Frequency Response for Characterization of Compliant Interface Elements on Vibration Test Benches

open access: yesApplied Sciences, 2021
In vibration tests, the behavior of the structure depends on its mechanical boundary conditions, which are represented in physical tests by connecting elements with mechanical properties.

Bijective Mappings Of Meshes With Boundary And The Degree In Mesh Processing [PDF]

open access: yes, 2014
This paper introduces three sets of sufficient conditions, for generating bijective simplicial mappings of manifold meshes. A necessary condition for a simplicial mapping of a mesh to be injective is that it either maintains the orientation of all ...

On evaluating the inf-sup condition for plate bending elements [PDF]

open access: yesInternational Journal for Numerical Methods in Engineering, 1997
Summary: We address the evaluation of the inf-sup condition for Reissner-Mindlin plate bending elements. This fundamental condition for stability and optimality of a mixed finite element scheme is, in general, very difficult to evaluate analytically, considering for example distorted meshes. Therefore, we develop a numerical test methodology.

On the circumradius condition for piecewise linear triangular elements [PDF]

open access: yesJapan Journal of Industrial and Applied Mathematics, 2015
We discuss the error analysis of linear interpolation on triangular elements. We claim that the circumradius condition is more essential then the well-known maximum angle condition for convergence of the finite element method. Numerical experiments show that this condition is the best possible.
