Purpose – 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. Design/methodology/approach – Cauchy stress vectors and a Runge‐Kutta algorithm are used to identify the...
Purpose – 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 translational and rotational units variously arranged according to different configurations, by using the...
Purpose – 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 flow simulations with the open boundary based on moving boundary method. Design/methodology/approach...
Purpose – 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 flow heads. The pressure pulses in the runner blade passage were predicted numerically for both moderate...
Purpose – 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 (CHMT) model is able to analyze statistical character of coefficients, which means they can be...
Purpose – The purpose of this paper is to model the strain localization in J 2 materials with damage evolution using embedded strong discontinuity modes. Design/methodology/approach – In this procedure, an heuristic bandwidth scale is adopted to model the damage evolution in the shear bands....
