- A numerical approach for linear analysis in solid mechanics based on the finite element methods is presented. Continuum finite elements as well as special structural elements are derived. The advantage of the numerical approaches in comparison with classical analytical methods is demonstrated. The efficiency and accuracy of the finite element approach are demonstrated by numerical examples.
- Student responsibilities:
- Grading and evaluation of student work over the course of instruction and at a final exam:
- Evaluation of the project assignments (20%). Evaluation of the results achieved at the colloquia or oral and written exams (80%).
- Methods of monitoring quality that ensure acquisition of exit competences:
- The verification of the student attendance at the classes and evaluation of the personal commitment of the students at the laboratory exercises. Evaluation of the results, theoretical understanding and the quality of the presentation of the project assignments. Evaluation of the results achieved at the colloquia or exams. Survey of the output data of the official university questionnaires completed by the students at the end of the course.
- Upon successful completion of the course, students will be able to (learning outcomes):
- Understand and derive the variational formulation of the finite element method. Understand and derive the global finite element equation. Understand and discuss the convergence of the solution and the organization of computational programs. Understand and derive one-dimensional finite elements. Understand and derive two-dimensional finite elements. Understand and derive three-dimensional finite elements. Understand and derive plate and shell finite elements. To be capable to apply finite elements in structural analysis and to assess the computational errors.
