Academic sessions are based on well-balanced scientific and technical training, as well as a solid background in communication, management and English language training. From this wide-ranging viewpoint, as a future engineer you will be able to define and solve problems in a multidisciplinary environment.
This multi-disciplinary training, which has a strong foundation in Science and Technology, gives you the ability to adapt methods to current and future needs.

Our engineering students follow a Cooperative Education programme with work-linked training periods and academic sessions with an equal amount of time being devoted to each.
Initial download of the metrics may take a while. In such a situation, it is not easy to have resorts to structural finite-elements analysis which requires important means of calculation and lot of time.
The current usage metrics is available hours after online publication and is updated daily on week de.

Created at the request of Conformity Assessment companies and major industrial groups in the construction engineering sector; the Civil Engineering Department trains engineers diemnsionnement design, construction, management and the maintenance and technical assessment of structures. During the first stages of dimensioning of an engine, we must define major dimensions in particular those related to the crankshaft.
Owning the CAD of the crankshaft of a four cylinder engine and the real loading along the combustion cycle we calculate with the dimensionneent element method the reactions in the crank journals. Renseignements et candidature sur www. This methodology is simple and efficient to be used during quasi static calculations of the crankshaft. Data correspond to usage on the plateform after The suitable choice of these coasts, dimensioning for other parts, requires several iterations.
Using a simplified model based on beam theory can be useful, fast and sufficiently accurate.
This work presents a methodology of identification of the geometrical characteristics of the equivalent elliptic cross-sections which must behave like the real crankshaft.
