Objectives

The student will master the fundamental concepts of numerical methods and will have the ability to perform numerical modelling of technological processes such as bulk metal forming, sheet metal forming and machining by using commercial codes and related pre and post processing tools. By the end of the semester, students should: 1. be acquainted with the methods used in numerical modelling programs: finite difference method and finite element method; 2. be able to use pre-processing, analysis and post-processing tools, which are necessary to the numerical simulation; 3. be able to create the numerical model of practical situations obtained by metal forming: analysis and criticism. Students should also be able to analyse results, identify malfunctions and find solutions to them.

Learning outcomes and competences

The following skills are expected to be developed:

- aplication of different numerical methods to perform numerical modelling of technological processes and understanding of corresponding advantages or limitations;

- performing successfully every step of a technological process numerical simulation  

- characterization of metallic materials, definition of suitable constitutive equations and parameter determination based on existing experimental tests

- integration of different areas and topics of mechanical engineering, such as numerical methods, solid mechanics, behaviour and material characterization, fabrication processes, etc.

- analysis, discussion of numerical results and aptitude to relate them with both numerical and process parameters, in order to find an optimization route to expected results.

- team work and development of writen and oral presntation skills.
