This paper presents one of the soft computing methods, specifically the artificial neural network technique, that has been used to model the temperature dependence of dynamic mechanical properties and visco-elastic behavior of widely exploited thermoplastic polyurethane over the wide range of temperatures. It is very complex and commonly a highly non-linear problem with no easy analytical metho...

The emulsion explosive is one of the important industrial explosives. The structural stability of the water-in-oil (W/O) emulsion matrix of an emulsion explosive determines the reliability of its initiation, safety and detonation performance. It is known that the emulsifier is one of the most important factors affecting W/O structural stability. In this paper, several emulsifiers with the funct...

Abstract The present paper analyzes an unsteady magnetohydrodynamic blood flow model of visco-elastic fluid through inclined porous stenosed artery with body acceleration and slip effect. Navier-Stokes equations have been used to describe the model. governing equation is solved by analytic method considering as incompressible, fluid, suspension RBC’s in plasma. Axial velocity, acceleration, rat...

Centrifugal compaction causes changes in the surface properties of bacterial cells. It has been shown previously that the surface properties of planktonic cells change with increasing centrifugal compaction. This study aimed to analyze the influences of centrifugal compaction and environmental conditions on the visco-elastic properties of oral biofilms. Biofilms were grown out of a layer of ini...

This article deals with the dynamic behavior of highly contrasted stratified (HCS) plate made elastic or visco-elastic, symmetric non-symmetric, layers. Such composite structures may correspond to laminates plates sandwich panels often use in engineering. The study is based on synthetic analytical HCS model derived by asymptotic approach (Boutin and Viverge 2016). physical mechanisms within are...

the high blood rate that often occurs in arteries may play a role in artery failure and tortuosity which leads to blackouts, transitory ischemic attacks and other diseases. however, vibration and instability analysis of carotid arteries are lacking. the objective of this study is to investigate the vibration and instability of the carotid arteries conveying blood under axial tension with surrou...

We perform a multiscale analysis of the backscattering properties of a complex interface between water and a layer of randomly arranged glass beads with diameter D=1 mm. An acoustical experiment is done to record the wavelet response of the interface in a large frequency range from lambda/D=0.3 to lambda/D=15. The wavelet response is a physical analog of the mathematical wavelet transform which...

We show that continuum models for ideal plasticity can be obtained as a rigorous mathematical limit starting from a discrete microscopic model describing a viscoelastic crystal lattice with quenched disorder. The constitutive structure changes as a result of two concurrent limiting procedures: the vanishing-viscosity limit and the discrete-to-continuum limit. In the course of these limits a non...
