051135 - DIGITAL MANUFACTURING [IC]
The VIRTUAL MANUFACTURING course aims at preparing students with the theoretical knowledge and practical skills required for an advanced use of numerical simulations with the Finite Element Method (FEM), as currently used for the design of metal forming and removal processes. It initially provides the students a framework of modern techniques and applications of virtual manufacturing. Then, it provides the essential theoretical foundations use of FEM simulation on the behavior of solids under large plastic deformation and fracture. The main peculiar issues of the simulation of massive and sheet plastic deformation processes and of material removal processes.
Risultati di apprendimento attesi
The students will have the basic knowledge on the fundamentals of Finite Element Simulation. The students will be able to use some professional software packages for the FEM simulation of the main manufacturing processes. Besides, they will have the ability to quickly learn any new simulation software they will need to use in their future working life.
Introduction to virtual manufacturing methods and applications; the simulation of manufacturing processes and machines
Analytical modeling of manufacturing processes: Fundamentals of plasticity of metals: yield criteria, hardening laws
FEM simulation of materials at large deformations: the finite element method, visco-plastic approach and implicit integration under stationary conditions, elastic-plastic approach with explicit time integration under transient conditions
FEM simulation of bulk metal forming processes: selection of elements, mesh building, contact problem, remeshing algorithms, thermal conduction, tools and dies elasticity
FEM simulation of material removal processes: fracture criteria, tool wear models, heat exchange problems at the tool-chip interface, contact problem
FEM simulation of sheet and tube forming processes: selection of elements, meshing and remeshing criteria, contact algorithms, elastic springback, fracture criteria
Organization The course is based on a mix of theoretical and practical lessons. Many hours of training are provided on the computer, while learning the use of some large commercial software packages for virtual manufacturing.
The students need to have some fundamentals of solid mechanics at large deformations
Modalità di valutazione
Students will have to carry out, in small groups, a process simulation project that allows to check the application of knowledge and understanding. The final test will be a brief oral discussion that includes the presentation of the project to check also the knowledge and understanding of the candidate.
