Assembly and tribology: finite elements modeling

3MAK6 Assembly and tribology: finite elements modeling Materials and Chemistry S9
Lessons : 14 h TD : 0 h TP : 12 h Project : 0 h Total : 26 h
Co-ordinator : Sophie Eve
Prerequisite
Non renseigné
Course Objectives
Presentation of the different assembly technologies of parts (especially metallic parts), including notions on interface and adhesion, and the concepts of friction, wear and lubrification.
Syllabus
- Description of the different usual assembly technologies : welding, mechanical assembly (screw, rivet,…), sticking. Choice of the best adapted process. State of the interface et precautions that have to be taken.
- Contact mechanics, Hertz's theory, thermal aspect. Wear mechanisms, friction materials and contacts lubrification.
Practical work (TD or TP)
Practicals (3x4h) in numerical simulation associated to the proposed lecture would allow to initiate to the explicite analysis of contact modeling modélisation du contact, and also to start with non linear simulations (elasto-plastic, visco-elastic materials) and modal analysis (determination of the resonance frequencies and buckling).
Acquired skills
Understanding of the mechanisms taking place at the interface between two materials or systems. Review of the different assembling technologies. Initiation to tribologie including contact mechanic, study of adhesion, wear, friction and lubrification.
