The course is aimed at engineering students who want to deepen the
typical problems of bulk plastic deformation. After an introductory part,
dedicated to understanding the behaviour of materials under plastic
deformation and energy theorems valid in this context, some of the most
significant technologies used in the field of bulk plastic deformation
processes will be described.
The numerical methods for the resolution and optimization of bulk plasticTipo testo Testo
deformation processes will also be described.
