SIMULATION: HOT FORMING
The forming of sheets at high temperatures has gained prominence in recent years, especially in the car industry. It makes it possible to obtain pieces with high mechanical properties in relation to the weight and to reduce negative phenomena related to the cold forming process, such as spring-back.
The numerical simulation using finite elements in this field is an essential tool for the adjustment of this kind of process, as well as for other processes such as forging, extrusion, lamination, etc.
The numerical simulation using finite elements allows us to study, among others, the following aspects of the hot forming process:
- Thermomechanical study of the tools:
- Distribution of temperatures and tensions in the tools during the forming cycles.
- Design and analysis of the cooling systems.
- Selection of materials.
- Stabilisation cycles of the process.
- Thermomechanical study of the piece:
- Study about the conformability and selection of the suitable format.
- Forecasting of the distribution of temperature and final mechanical strength.
- Research into new hot forming processes.
