Aims

The course gives a theoretical knowledge of the various concepts or theory related to the forming of metals: macroscopic theory of plasticity, mechanisms of microstructure evolution, cristallographic textures, residual stresses, tribology, forming limits. It offers the the possibility to use a finite element code for simulating forming operations. It also introduces to the key technological issues involved in the most common metal forming processes.

Main themes

The course is divided in three parts. The first part consists in an introduction to the phenomenological theory of plasticity (J2 déformation theory, J2 flow theory, Hill anisotropic theory), cristal polycristal theory of plasticity.

The second part concerns the other important phenomena taking place during a forming operation : textures, residual stresses, microstructural evolution, contacts and wear, forming limit diagrams.

The third part introduces to the most technologically important forming processes : rolling, extrusion, drawing, deep drawing, forging.

Content and teaching methods

Part I. Plasticity theory

Part II. Other phenomena taking place during forming operations

Part III. Introduction aux principaux procédés de mise en forme

Projects by groups about specific important forming operations
