Most hydraulic, thermal and energy (turbine, pump, turbo-jet engine, ...) used in many sectors (transport, energy, ...) are composed of mechanical sub-assemblies, some of which are particularly sought. These systems will experience during their term of service appeals to maintenance or suffer damage. The objectives of this module are so focused on the analysis of the limiting phenomena of life (seed and crack for example) of these systems for which it is to anticipate the interventions on critical parts. These objectives also have many applications in the steps of sizing systems and equipment in connection with their technical specifications if these phenomena are integrated upstream studies.
The first part of the course focuses on the case of mechanical structures for beyond the elastic limit but below the threshold of failure. Irreversible deformations contained which can be translated by the instantaneous elastoplasticity treated. This course is anchored on the description of the macroscopic behavior while the deformation mechanisms are just mentioned. The laws being associated nonlinear recourse to numerical computation behavior is quickly become indispensable. Students completing this course are prepared to conduct elastoplastic calculations on structures by the finite element method (as described in "Getting work finite element software BE"). The second part of the course is devoted to mechanical structures subjected to ultimate stress causing cracking and breakage. Often these structures are found in the field of high pressures, high temperatures, or when fatigue is present. Understanding the mechanisms that induce the destruction of a mechanical system will predict the limiting values ??of operating parameters, estimate the lifespan, choosing the right material for a given application.
The ideas and concepts covered in class will be implemented through activities of case studies and modeling by finite element method (ANSYS and ABAQUS).Prerequisites
