1.1 Various hot compression modes

Hot compression is available in several versions:

• uniaxial compression ;

• flat compression bi-piercing ;

• flush-mounted compression ;

• high-temperature flat compression ;

• multiaxial compression .

Each of these systems offers deformation paths suitable for simulating industrial processes such as free-edge forging, rolling and so on. For tension, the classic uniaxial assembly is used. In compression, as in tension, the cylinder's displacement speed must...
