DR Congo with the National Program for Space and Technological Research (PNRST), is the subject of improvement of structure of satellite own the himself. The problem is to simulate and model the structure from the point of view viscoplasticity, vibration and cryogenic behavior at very high altitudes. Sizing will be facilitated by the following approach: 1. cracking among the modes of ruin of structures; 2. the mechanics of fracture among models dealing with the cracking of structures; 3. finite element methods among numerical methods applicable in fracture mechanics.
Author Keywords: modeling, structural mechanics, numerical methods, finite element methods, satellite.

Abstract

The problem is to simulate and model the structure from the point of view viscoplasticity, vibration and cryogenic behavior at very high altitudes. Sizing will be facilitated by the following approach: 1. cracking among the modes of ruin of structures; 2. the mechanics of fracture among models dealing with the cracking of structures; 3. finite element methods among numerical methods applicable in fracture mechanics.

Abstract: (french)
La RDC avec le programme national de recherche spatiale et technologique (PNRST), fait l’objet de l’amélioration de la structure du satellite propre à elle-même. La problématique est de simuler et modéliser la structure du point de vue viscoplasticité, vibration et comportement cryogénique à des très hautes altitudes. Le dimensionnement sera facilité par l’approche suivante : 1. La fissuration parmi les modes de ruine des structures ; 2. La mécanique de la rupture parmi les modèles traitant de la fissuration des structures ; 3. Les méthodes des éléments finis parmi les méthodes numériques applicables en mécanique de la rupture.
Author Keywords: modélisation, mécanique de structure, méthodes numériques, méthodes des éléments finis, satellite.
