An iterative approach for modal analysis of solid rocket motor incorporating frequency dependent modulus
modal analysis eigenfrequency frequency dependent modulus
2014/5/19
The modulus of viscoelastic materials varies with excitation frequency.However,during modal analysis of frequency dependent materials,a material evaluation frequency is necessary because stiffness can...
Non-modal analysis of the diocotron instability. Plane geometry
Non-modal analysis the diocotron instability Plane geometry Plasma Physics
2012/5/31
The comprehensive investigation of the temporal evolution of the diocotron instability of the plane electron strip on the linear stage of its development is performed. By using the Kelvin's method of ...
Multi-modal analysis for low energy neutron-induced fission of 235U
235U (n, f) multi-model prompt neutron fragment property
2009/12/24
Low energy neutron induced fission of 235U is studied in the framework of the multi-modal fission model. The fission fragment properties, such as the yields, the average total kinetic energy distribut...
Modal analysis and coupling in metal-insulator-metal waveguides
coupling metal-insulator-metal waveguides
2015/8/10
This paper shows how to analyze plasmonic metal-insulator-metal waveguides using the full modal structure of these guides. The analysis applies to all frequencies, particularly including the near infr...
Simple Modal Analysis Method for Multi-Mode Fibers
Simple Modal Analysis Method Multi-Mode Fibers
2015/7/16
We demonstrate a simple technique to measure the modal content of a multi-mode optical fiber by using a tunable source and a camera, and processing the near-field images measured at the fiber output.
A Modal Analysis of Coastally Trapped Waves Generated by Tropical Cyclones
Coastally Trapped Waves Tropical Cyclones shallow-water equations
2008/12/12
The authors use numerical simulations of the shallow-water equations to study the generation of coastally trapped waves by localized forcing mechanisms. The model parameters are chosen to be typical f...
