Learning outcomes of the course unit

Prerequisites

Planned learning activities and teaching methods

Assesment methods and criteria linked to learning outcomes

The graded course-unit credit requirements :

- active participation in seminars,

- knowledge check in the form of a test task,

- individual preparation and presentation of seminar assignments,

- good results in the written test of basic knowledge.


The teacher will specify the specific form of assessment in the first week of the semester.

Attendance at practical training is obligatory. Attendance is checked systematically by the teachers, as well as students’ active participation in the seminars and fundamental knowledge. Unexcused absence is the cause for not awarding the course-unit credit.

Language of instruction

English

Aims

The objective of the course is to present theoretical background of FEM and its practical application to various problems of continuum mechanics. Practical training is done with the commercial FE system ANSYS, which is frequently used at universities, scientific institutions and industrial companies worldwide.

Students gain basic theoretical and practical knowledge of the Finite Element Method. They learn how to use it for solving continuum mechanics problems in complicated two- and three dimensional regions. The acquired knowledge is applicable in all areas of solid mechanics, for students of all branches of engineering study.
