Floquet Theory for Discontinuously Supported Waveguides

Modelling and Simulation in Engineering, 2016
We apply Floquet theory of periodic coefficient second-order ODEs to an elastic waveguide. The waveguide is modeled as a uniform elastic string periodically supported by a discontinuous Winkler elastic foundation and, as a result, a Hill equation is ...

Shape Analysis of Elastic Curves in Euclidean Spaces [PDF]

IEEE Transactions on Pattern Analysis and Machine Intelligence, 2011
This paper introduces a square-root velocity (SRV) representation for analyzing shapes of curves in euclidean spaces under an elastic metric. In this SRV representation, the elastic metric simplifies to the IL(2) metric, the reparameterization group acts by isometries, and the space of unit length curves becomes the unit sphere.

Comparison of Performance Analysis Results with Developed Site-Specific Response Spectra and Turkish Seismic Design Code: A Case Study from the SW Türkiye Region

Buildings
On 6 February 2023, the Kahramanmaraş earthquakes clearly showed that the elastic spectrum curves in TBEC-2018 are insufficient to represent earthquake behavior.

High-accuracy compliance correction for nonlinear mechanical testing: Improving Small Punch Test characterization

Nuclear Materials and Energy, 2021
Small punch test, SPT, of metallic materials is a very convenient mechanical test since it requires a small volume of material. However, SPT data from different laboratories suffer from large scatter, mainly due to the different experimental set-ups ...

Eurofer97 Creep-Fatigue assessment tool for ANSYS APDL and workbench

Nuclear Materials and Energy, 2018
For the design of future fusion reactors the ferritic-martensitic steel Eurofer97 is the main candidate for in-vessel structural application to be able to withstand harsh environment like irradiation and cyclic loading under elevated temperatures.

Determining the constitutive behavior of nonlinear visco-elastic-plastic PMMA thin films using nanoindentation and finite element simulation

Materials & Design, 2021
Understanding the nonlinear visco-elastic-plastic behavior and properties of PMMA thin films during nanoindentation is helpful for predicting the plastic deformation of thermoplastic polymer products during manufacture and evaluating stress to predict ...

Liquid-assisted tunable metasurface for simultaneous manipulation of surface elastic and acoustic waves

AIP Advances, 2018
A tunable and multi-functional one-dimensional metasurface, which is formed by engraving periodic semi-ellipse grooves on the surface of an aluminum half-space, is proposed in this paper. One characteristic of the metasurface is the manipulation of multi-

Elastic magnetic curves of ferromagnetic and superparamagnetic models

Mathematical Methods in the Applied Sciences, 2020
In this paper, new energy functionals are described via the variational approach method. By doing this, a new class of elastic curves is described in the three‐dimensional ordinary space. An alternative method is also investigated to compute critical points of the bending energy functionals acting on a class of magnetic curves. Then, classifications of
