Interaction élastique dislocation – joints interphases dans des matériaux de structure cubique à faces centrees
(جامعة الإخوة منتوري قسنطينة, 2017-02-23)
The majority of materials mechanical properties are due to the crystalline defects interactions, in particular the interaction between dislocations and interfaces. The interaction energy between a dislocation and an ...
Optimisation et dimensionnement d’un système de dessalement performant
(جامعة الإخوة منتوري قسنطينة, 2017-02-23)
"Solar distillation is an interesting solution for the supply of drinking water in arid and / or
isolated areas. However, the production of conventional solar stills remains insufficient.
Therefore, and in order to improve ...
Prédiction à partir des différentes phases cristallines des propriétés physiques et mécaniques des céramiques dentaires
(جامعة الإخوة منتوري قسنطينة, 2017-06-22)
We have used the pseudo-potential and plan wave method (PP-PW) based on density functional
theory (DFT) to examine the physical and mechanical properties of dental ceramics systems based
