Learning outcomes of the course unit

The students will be made familiar with the advanced application of the finite-element method emphasising the solution of nonlinear structural and structural dynamics problems.

Prerequisites

Students are expected to have knowledge acquired in completed course Finite Element Method and the ANSYS I (RA1) and the courses in Mechanics of Solids (Statics, Dynamics, Strength of Materials). Also required is the knowledge of classification of force systems and their resultants, equivalent force systems, body supports and connections, their computational models, general theorems of linear elasticity, stress in body point, linear vibration of systems with one and n degrees of freedom, the basic concepts of the linear algebra, vector calculus, differential calculus and numerical mathematics are suspected. Students should be able to solve a linear static analysis in ANSYS software.

Co-requisites

Not applicable.

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.

Assesment methods and criteria linked to learning outcomes

Course-unit credits are awarded on the condition of: active participation in the seminars, defence of the given semester work, the oral part of graded-course unit credit classified at least by grade E. Seminar tutor will specify the form of these conditions in the first week of the semester.

Aims

The objective of the course is to familiarise students with advanced procedures of finite element method applied for solution of nonlinear structural and structural dynamics problems. Students will use ANSYS to explore the basic principles of nonlinear solutions by using finite element method.

Specification of controlled education, way of implementation and compensation for absences

Attendance is required. One absence can be compensated for by attending a seminar with another group in the same week, or by elaboration of substitute tasks. Longer absence may be compensated for via special tasks according to instructions of the tutor.
