Dynamic stability of an elastic beam with visco‐elastic translational and rotational supports

C.E. Majorana, B. Pomaro

The purpose of this paper is to show how to find the regions of dynamic instability of a beam axially loaded and visco‐elastically constrained at its ends by Kelvin‐Voigt…

On the modeling of shear bands formation in J2 materials with damage evolution

Sebastian D'hers, Eduardo N. Dvorkin

The purpose of this paper is to model the strain localization in J₂ materials with damage evolution using embedded strong discontinuity modes.

Experimental and numerical analysis of blade channel vortices in a Francis turbine runner

Xiao Yexiang, Wang Zhengwei, Yan Zongguo

The purpose of this paper is to investigate, experimentally and numerically, the pressure pulse characteristics and unsteady flow behavior in a Francis turbine runner for moderate…

A static image coding algorithm based on contourlet Classified Hidden Markov Tree model

Fan Yonghui, Wang Gang, Liang Xiao

Because of advantages such as multi‐scale and multi‐direction, contourlet transform is better at treating a 2‐D image than wavelet transform and the Classified Hidden Markov Tree…

Numerical analysis of a miniaturised cold gas thruster for micro‐ and nano‐satellites

Aleksander Grm, Tor‐Arne Grönland, Tomaž Rodič

The purpose of this paper is to describe the micro fluid flow analysis in a micro thruster of micro‐/nano‐ satellite propulsion system and to propose the algorithm for the fluid…

An algorithm for defining load paths and a load bearing topology in finite element analysis

Donald W. Kelly, Carl A. Reidsema, Merrill C.W. Lee

The purpose of this paper is to describe a post‐processing procedure for defining load paths and a load bearing topology using the stresses from a finite element analysis.
