Finite Element Methods (FEM) (3 cr)

Objective

The students understand the theoretical basis of the finite element method. They are able to conduct static FEM analysis on structures, interpret the results and draw conclusions.

EA-EN EUR-ACE Engineering analysis: Students are able to create a model of the structure which is appropriate for FEM analysis. They are also able to complete the analysis.

EA-ER EUR-ACE Engineering practice: Students are able to choose a correct method and element type for a structural analysis. They are also able to interpret the results and draw conclusions based on the results.

Content

Theoretical basis of the finite element method: forming the stiffness matrix and solving the system of equations. Element types: truss, beam, shell and solid. Analysis types: static and modal analysis. Interpretation and sharpness of the results. Linear and non-linear analysis. Modeling assemblies and contact surfaces. Using a FEM-software.

Exam schedules

Course exam and 2 re-sits (if needed) in December.

Student workload

Lectures and exercises 39 h. Independent study 42 h. Total 81 h.
Campus online courses only independent study 81 h.

Assessment criteria, satisfactory (1)

Pass:
Student has calculated correctly at least 60% of homeworks
Fail:
Student has not calculated correctly 60% of the homeworks. To get evaluation by number the student must take part for supervised exam.
Excellent (5): The student masters the topics of the course, and he is able to apply them innovatively in challenging engineering applications.

Very good (4): The student masters the essential knowledge of the course, and he is able to apply his skills to usual engineering problems.

Good (3): The student masters the basic principles of the course, and he is able to solve basic engineering problems.

Satisfactory (2): The student is familiar with the basic knowledge and terminology of course, but he has some problems with applying the knowledge. He can nevertheless solve simple engineering problems.

Adequate (1): The student is familiar with the basic knowledge and terminology of the course, but he has significant problems with applications.

Qualifications

The technical beam theory: stress and deformation caused by the normal and shear force and the bending moment.

Further information

Campus online course is graded as approved / rejected. In order to include this course to a study program, a course exam has to be completed for numerical grading. The exam and re-sits are arranged in December.
