Learning outcomes of the course unit

The course outputs are practical skills on modeling mechanics tasks by using Finite Element Method. Student has basic knowledge about program system ANSYS. Student can analyze assigned problem and make out computational model. Student is able to solve basic static and dynamic tasks. Student gets more realistic conception of behavior of selected civil engineering construction types. Student is able the theoretic FEM knowledge use at solving particular mechanics tasks.

Prerequisites

Manage PC, theory of structural mechanics, fundamentals of mathematical theory of elasticity, fundamentals of structural dynamics, finite elements method

Co-requisites

Planned learning activities and teaching methods

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations.During lectures, standard model of theory explanation using the projector and blackboard is used. In the training course students work individually with the computer and themselves solve problems and they write notes in their workbook.

Assesment methods and criteria linked to learning outcomes

Conditions to get credit are active presence in training course (two absences are allowed) and successful evaluated of the test. Test is consists of both theoretical questions and practical tasks.
