Objectives of the course
The course aims to deepen the engineering problems in the field of metallic materials machanical working, invoking the reference frame on the productive processes for the mechanical industry already acquired during the 1st level studies and developing in depth both the physical principles and the analysis methods concerning to bulk forming and metal sheet forming processes.
Expected skills
At the end of the course students will be able to analyze several type of working based on plastic deformation, occurring either at cold or hot temperatures, to demonstrate their understanding of related physical principles, as well as the ability of sizing the technological parameters and assessing the performance in light of the behavior of their equipment.
Prerequisites
Calculus I, Calculus II, Linear algebra, Physics, Technical communication methods, Logistics and Industrial Production, Mechanics, Probability and statistics, Introduction to theoretical and applied mechanics, Electrical machines, Fluid Mechanics, Mechanics of materials, Applied mechanics and machines, Heat transfer, Materials for Engineering, Industrial plants, Quality and Metrology, Mechanical Manufacturing Processes.
Syllabus
Plastic behavior of isotropic metallic materials and generalization of the characteristic curve. Metal flow strain-stress relationship in several conditions. Problems solving concerning the metals' plastic deformation, thin element method; slip-slines method; upper bound method; FEM methods. Bulk forming processes and related equipments: forging, heading and pressing, rolling, drawing and extrusion. Metal sheets forming processes and related equipments: shearing, bending, drawing, stamping.
Laboratories and/or exercises
The activities will focus on practical applications about arguments developed at lesson. In particular, during the classroom practice students face several problems concerning the design and technical specification of the processes handled at lesson. A set of laboratory activities are conducted using CAE tools - aimed to develop a specific design skill in the bulk forming processes field - and using simple tools for computer calculus (spreadsheet), aimed to dimension and plan the plastic deformation problems for the main categories of processes.
The student must prepare an individual report about their own work, including the detailed resolution of problems proposed.

Revisions / Exam
The degree of learning evaluation that a student has acquired is based on three elements:
- The individual report prepared by the student during laboratory practice, aimed to quantify its ability in developing the working processes;
- A written test about 2 hours lasting, which aims to identify the capacity to face problems of plastic deformation similar to those developed during the practice;
- An oral test, in order to establish the student's theoretical performance as well as its ability to conceptually discuss the proposed topics doing the necessary scientific and logical links between the physical quantities involved.
