Course description: Course objectives:
The purpose is to provide students with application of the finite element method in analysis and design of complex mechanical structures. Besides statical analysis, the basics of dynamical and thermal analysis are presented. The computer exercises include use of commercially finite element software package. The efficiency and accuracy of the numerical computations are demonstrated by examples from engineering practices.

Enrolment requirements and required entry competences for the course:
Numerical Analysis of Structures is a continuation of the course Finite Element Method. Upon successful completion of this course (course taken but not necessarily passed), students may enroll in Numerical Analysis of Structures (Finite Element Method passed requirement for taking the exam). Students should also have good background in the basic courses of Solid Mechanics, Structural Dynamics, Mechanical Vibrations, Thermodynamics and Structural Stability.

Student responsibilities:
Students are expected to attend and actively participate in every lecture and lab. Lecture and exercise attendance is monitored. Each student need to complete course work that requires both hand calculation and computer simulations. Computer simulations should be performed by using finite element program. After students have successfully completed their course work, they have to take the written exam and achieve a score of 50% to pass and to take the oral exam.

Grading and evaluation of student work over the course of instruction and at a final exam:
Assessment: 5% attendance, 35% course work, 35% written examination (a twohour written examination at the end of the course), 25% oral examination (a 30 minutes oral examination at the end of the course).

Methods of monitoring quality that ensure acquisition of exit competences:
The teaching and learning methods provide knowledge and understanding as well as intellectual and practical skills. The learning outcomes relating to this course are assessed by course work and examination. The course work is used to assess the student"s ability to use advanced Finite Element Analysis (FEA) techniques to model and to solve practical problems. The learning outcomes related to FEA knowledge, understanding and use of numerical principles are tested in the written and oral examination. In order to improve the quality of teaching of the course, all students fill out a teachercourse evaluation questionnaire at the end of semester.

Upon successful completion of the course, students will be able to (learning outcomes):
