The distributions of stresses and deflection in rectangular isotropic and orthotropic plates with central circular hole under transverse static loading have been studied using finite element method. The aim of author is to analyze the effect of D/A ratio (where D is hole diameter and A is plate width) upon stress concentration factor (SCF) and deflection in isotropic and orthotropic plates unde...

In squeeze flow rheometry, the main problem is the boundary condition between the squeezed material and the plates. So, the crucial assumption is to know the location and the shape of the sample part where wall slip may or may not occurs. This question is investigated from experimental results. For this, squeeze flow experiments are carried out to visualize the flow pattern at the walls. Influe...

An experimental and theoretical investigation of the acoustic and vibrational properties of orchestral crotales within the range C6 to C8 is reported. Interferograms of the acoustically important modes of vibration are presented and the frequencies are reported. It is shown that the acoustic spectra of crotales are not predicted by assuming that they are either thin circular plates or annular p...

This article presents a prototype of an application for the analysis of cDNA/gene expression data and contribution for genome annotation from macroarrays. The application described here allows the quantification of a set of experiments with macroarrays of the same size. It generates html reports, easily shared, showing the expression of genes contained in each membrane and a global report compa...

based on two-dimensional plane stress and bifurcation functional from hill's general theory in polar coordinate the critical condition for elastic wrinkling of the flange of a circular blank ( the wave number in the flange and wrinkled area) during the deep-drawing process are obtained analyticaly to improve the previous given results. in this analytical study, the elastic limitation of the mat...
