Course detail
Simulation of Technological Processes
FSI-HPR Acad. year: 2019/2020 Summer semester
The course content is to acquaint students with basic information about the selected numerical methods used in current technical practice and a deeper understanding of the finite element method. In the lectures, students are mainly acquainted with the theoretical basis and the FEM concept in the area of stress-strain and temperature problems solving, which are closely related to the problems of forming, welding and heat treatment of the material. The practical part – the practice aims primarily at the general principles of the creation of FEM calculation models, designed for the analysis of technological processes. Thus, students gain basic knowledge for independent orientation in the problems of numerical simulations and analyze using the finite element method.

Learning outcomes of the course unit
Students will be acquainted with theory as well as with the latest knowledge in the field of numerical simulations, especially with the finite element method. They will acquire necessary skills for formulation and solution of FEM computational models in the areas of forming, welding and heat treatment of the material.
Prerequisites
Basic knowledge of manufacturing technology and basic computer skills.
Planned learning activities and teaching methods
The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.
Assesment methods and criteria linked to learning outcomes
The final evaluation is based on the active participation in the class, i.e. active work with a selected FEM software and proof of theoretical knowledge in the form of a written test. It is classified by using the ECTS grading scale.
Aims
Aim of the course is to acquaint students with possibilities of the use of numerical simulation in the design of technological processes. Students gain an overview of practical competences targeted to the area of his/her topic of dissertation and a general view of the use of numerical simulations in technological practice and they will acquire the skills needed to work with simulation software based on the finite element method.
Specification of controlled education, way of implementation and compensation for absences
Attendance in lectures is recommended. Attendance in exercises is compulsory. The attendance to the seminar is regularly checked and the participation in the lesson is recorded. In case, that the lesson does not possible to participate, the teacher may in justified cases set an additional assignment.
