Aims of the course unit:

Aim of the course is to acquaint students with the possibilities of experimental and theoretical evaluation of production processes using computer aid and with basics of work in particular areas of this problematics. The students will have a view of what they can expect from computer aid results in practice. The course also aims to acquire the skills necessary to basic work with simulation software in these areas.

 

Students will be acquainted with theory as well as with the latest knowledge in the field of 3D optical measurement, virtual manufacturing and numerical simulations. They will acquire necessary skills for formulation and solution of computational models in the areas of forming and welding.

Course contents:

The course acquaints students with the possibilities of computer aid in various areas of manufacturing design, especially with the use of 3D optical measurement and numerical simulation as tools for analysis and optimization of technological processes. In the lectures, students are introduced to the nature of the use of computer aid and numerical simulations for solving stress-strain and temperature problems, which are closely related to the issues of forming and welding technologies. Exercises aim primarily at practical calculations and mastering the main principles of computational models creating. Therefore, students will gain an orientation in the field of numerical simulations and analyses using the finite element method.
