Goals

Structure calculations (ME and IEN):
------------------------------------
This course sessions and associated BE aim to strengthen the implementation of solid finite element codes according to the nature of the case study: Presentation of different models for the calculation of structures and choice of representation that best suits the room and dimensioning problem posed.
Analysis of materials in service (ME and IEN):
----------------------------------------------
This course focuses on the description of service experienced by materials commonly implemented in hydraulic and thermal systems (turbine, pump, jet engine, etc.). For each type of system, the specifications and materials is presented possible solutions discussed. The aim is to develop a mastery of the analysis and design of systems through a specification, this written in context of the implementation of suitable materials.

Materials for Nuclear (only for IEN):
-------------------------------------
The objective of this course is to introduce the key concepts in materials science, including the concepts of specific bases for structural materials (mainly metal alloys) and then present the specific materials use in a nuclear environment. The first part is to introduce the systematic approach to selecting materials illustrated in a simple case and then applied to case studies in the field of nuclear energy (duct or vessel) (BE 8am: 4h presentation of CES and 4h case study ). A second part will focus on the presentation of radiation damage (hardening, swelling, irradiation creep and growth) including a quantitative approach based on the calculated CCA (2h TD). A third part will be devoted to the study of specific simplified material aging of large components of PWR (mechanisms and phenomenological laws) (6h TD).

Structural Dynamics (only for ME):
----------------------------------
It is a question of formulating a problem of structural dynamics combining strength of materials (bars and beam elements) and continuum mechanics, these approaches aimed at analyzing the linear behavior. Furthermore, it is also able to obtain a discretized version of the problem using the Finite Element Method. The first examples of structures covered in class are cases that can be solved by hand. TPs associated with the pipeline include experimental demonstration of the phenomena of resonance vibration forced: determination of the two first 2 resonant frequencies, experimental demonstration of resonant modes, determination of structural damping in each mode. At the theoretical level: application of Lagrange equations for the development equation, calculation of natural frequencies, calculation of modal vectors, comparison experiment / theory.
