Auteur(s): Hassini, Abdelatif
Résumé: Detection of thermal anomaly prior to earthquake events has been widely confirmed by researchers
over the past decade. One of the popular approaches for anomaly detection is the Robust Satellite
Approach (RST). In this paper, we use this method on a collection of six years of MODIS satellite data,
representing land surface temperature (LST) images to predict 21st May 2003 Boumerdes Algeria
earthquake. The thermal anomalies results were compared with the ambient temperature variation
measured in three meteorological stations of Algerian National Office of Meteorology (ONM)
(DELLYS-AFIR, TIZI-OUZOU, and DAR-EL-BEIDA). The results confirm the importance of RST as an
approach highly effective for monitoring the earthquakes.2017-03-06T00:00:00ZThe Teaching of the CAD in the Curriculum of Graduation in TechnologyAchache, Habibhttps://ds.univ-oran2.dz:8443/jspui/handle/123456789/28812020-01-26T08:18:26Z2018-01-01T00:00:00ZTitre: The Teaching of the CAD in the Curriculum of Graduation in Technology
Auteur(s): Achache, Habib
Résumé: This work aims to study How to teach the CAD (computer- aided drawing) in higher education for
masters training level, then to propose, to assess the pedagogical devices established to facilitate the learning of
the CAD, And also to approach learning of the CAD via the 3D software. The proposals of the new method
will also be analyzed with higher education, and its need to integrate in masters degree program.In the
industrial sector, the training is largely irrelevant with reality, And students master level is low for all XAO.
The work aims to examine how to teach the CAD in master level in Algeria.IMSI of Oran (Industrial
Maintenance and Safety Institute) is a national institute, and therefore making this study, as if we did for the
whole of Algeria.The study was carried out on the curriculum of the five years of teaching with a balance
sheet, from the proposals will be put forward.2018-01-01T00:00:00ZStatic Modeling of the Delamination of a Composite Material Laminate in Mode IIAchache, Habibhttps://ds.univ-oran2.dz:8443/jspui/handle/123456789/28802020-01-26T08:09:27Z2018-01-01T00:00:00ZTitre: Static Modeling of the Delamination of a Composite Material Laminate in Mode II
Auteur(s): Achache, Habib
Résumé: The purpose of this paper is to analyze numerically by
the three-dimensional finite element method, using ABAQUS
calculation code, the mechanical behavior of a unidirectional and
multidirectional delaminated stratified composite under mechanical
loading in Mode II. This study consists of the determination of the
energy release rate G in mode II as well as the distribution of
equivalent von Mises stresses along the damaged zone by varying
several parameters such as the applied load and the delamination
length. It allowed us to deduce that the high energy release rate
favors delamination at the free edges of a stratified plate subjected to
bending.2018-01-01T00:00:00ZNumerical Analysis of the Behavior of Structures Damaged by Fatigue and Repaired by Composite PatchACHACHE, Habibhttps://ds.univ-oran2.dz:8443/jspui/handle/123456789/28792020-01-26T07:57:26Z2018-01-01T00:00:00ZTitre: Numerical Analysis of the Behavior of Structures Damaged by Fatigue and Repaired by Composite Patch
Auteur(s): ACHACHE, Habib
Résumé: In this paper, a numerical study of the behavior of fatigue cracks of damaged composite repaired aeronautical structures was presented. Various parameters have been highlighted such as effect of the dimensions and mechanical properties of the patch as well as the orientation of the fibers and the effect of the dimensions and mechanical properties of the adhesive. Two geometrical models have been proposed in order to see the influence of the crack position and the overall failure behavior under fatigue stress of the damaged structure. The results on the different geometric models of cracked plates and fissure plates from nicks show that composite patch repair is an effective technique for increasing plate strength, decreasing stress concentration and prolonging their service life.2018-01-01T00:00:00Z
