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.
Global warming is making our rivers become non-navigable during the dry season, following a considerable decline; pushing the population to lock up. It seemed interesting to us to try to overcome this insufficiency by initiating the calculation of a hydroplane leading to a prototype. In this article, we will have to calculate the conditions of resistance of the structure of the hydroplane in maximum load, using the relations of the nonlinear elasticity and the plasticity in fracture mechanics, based on the finite element methods.
