Summary
Manufacturing processes of plastic deformation are based on the fact that metallic materials have a very wide range over which deformations are irreversible. This shaping can be done at room or hot temperature to reduce the forces or deformation energies required. These techniques concern both profiles (solid products) and sheets (thin products). Although the origin of these techniques is very old, they are now of new interest, allowing the integration of sustainable development principles. Indeed, they allow to consider in a better way the performance of the materials and even to increase the performances by the strain-hardening generated at the shaping stage. This ultimately leads to the manufacture of lightweight parts or structures. If for a long-time empiricism and experience were essential, today the contribution of computer assistance tools and numerical simulations make it possible to optimize the design and manufacture of parts by these techniques. Fields concerned: automotive, aeronautics...
Educational goals
At the end of the course, the student will be able to: - Compare the different manufacturing processes by plastic deformation; - Consider the specificity of processes in the design of parts that meet specific functions; - To use an industrial parametric modeler (modeling, assembly, drawing, design of sheet metal parts); - To implement the entire process from design to the physical production of a functional prototype; - Understand and analyze the metallurgical and physical transformations generated; - Analyze process-material interactions; - Analyze the complementarity of deformation and cutting processes; - Carry out a technical study with technicians and professional engineers.

Continuous Assessment
Comments: - Presence and punctuality are part of the note;
- Behavior, interest, autonomy (just solicitation of teachers), progress of the work will be evaluated by teachers during the supervised sessions;
- Progress in the unframed session will also be appreciated (presentation at the beginning of the next session of what has been done in TEA);
- Quality of the delivered prototype (assembly, functional, weight, design, race, slalom...) and presentation of 5' with explanation of choices;
- Quality of the poster on a plastic deformation process and presentation of 5' followed by 15' of questions.
Online resources
- Engineering techniques; - Manufacturing videos; - Using the basic functions of a 3D modeler.
Pedagogy
Concerning teaching methods, this 96-hour teaching module is structured around three main themes: - Plasticity: lessons/TD/TP on the discovery of processes (forging, stamping...), on the plastic behavior and the simplified calculation method. In a team of 4 students, you will prepare and present yourself in the form of a poster a manufacturing process by plastic deformation of your choice. A competition for the best poster will be organized at the end of the module; - 3d modeling: you will use an industrial parametric modeler to model, assemble, propose an overall drawing and design sheet metal parts; - The project: in a team of 8 students, you will implement the entire process from design to the physical production of a functional prototype: a Halfbike, a half-bicycle to pedal upright! Half-bike, half-scooter, half-skateboard: the Halfbike combines running and cycling, you pedal standing up! It is composed of a frame with suspended rear wheels: mountainboard truck. The transmission is on the front wheel. The direction and braking are done via a mini handlebar. To turn, you just have to bend down. The fabrication of this prototype goes through stages of design, handling of the cutting and welding equipment, fabrication in the mechanical workshop of the central school, assembly with standard components and validation tests of the different characteristics. Indeed, tests in the form of a race and slalom will be carried out in the car park of the metal factory to validate the main characteristics of the prototype: the assembly criterion, the functional criterion, the weight, the design will be evaluated as well as a 5' presentation with explanation of the choices.
