This course builds on the first course linear modeling and takes one step further. This course delivers the skill set in non-linear structural modeling & analysis in the framework of the finite element method that is required to solve problems from the engineering practice. The weekly lectures and practicals impart both, practical experience with the modeling pipeline of commercial FE software and the theory fundamentals for the numerical approximation of non-linear engineering phenomena.
The majority of professionals in many branches of mechanical engineering will benefit from adding FEM to their skills array. The ability to develop modeling skills under supervision in a non-critical environment means that skills and techniques can be acquired in a logical, progressive manner.
The main topics of this course:
- nonlinear finite element method
- large displacements
- cohesive zone modeling
In this course students will gain:
- a strong theoretical understanding of non-linear FEM
- how to apply non-linear FEM to practical engineering problems
- efficient modeling and solution techniques
- understanding for the importance of verification and validation
While the previous course, linear modeling, is the required background, working professionals who are experienced with structural/stress analysis may choose to enroll directly in this course.
Computational methods in structural analysis are of prime importance in industry as tools to assess the efficiency and performance of structures in the field of aerospace, mechanical, civil and biomedical engineering. The reduced performance and destructive failure of structures is mostly due to the effects of small physical and geometric non-linearities. The combination of theoretical and practical knowledge in finite element analysis are valuable skills with which to address such problems in industry.
In order to efficiently model a real life engineering problem using finite element analysis and predict its future behavior, an engineer must possess a strong theoretical understanding of non-linearities in the finite element method (FEM) along with the understanding of the importance of verification and validation of such computational models.
On completing this course, you will have the skillset in non-linear (structural) modeling required to solve structural problems for industry with a special emphasis on implementation of small physical and geometric non-linearities. The course equips you with a theoretical background of non-linear FEM enabling you to develop finite element (FE) models for practical applications and correctly interpret their results.
The course uses an open source FE package in weekly practical sessions where you will model sample problems and validate your results against simplified analytical models or open literature.
Multiple assignments are provided, both theoretical and practical. Assignments may be altered to particular needs to develop competencies you are looking for.
The assessment of this course will be based on three assignments, two theoretical and one practical.
If you successfully complete your online course you will be awarded with a TU Delft certificate.
This certificate will state that you were registered as a non-degree-seeking student at TU Delft and successfully completed the course.
If you decide that you would like to apply to the full Master's program in Aerospace Engineering, you will need to go through the admission process as a regular MSc student. If you are admitted, you can then request an exemption for this course that you completed as a non-degree-seeking student. The Board of Examiners will evaluate your request and will decide whether or not you are exempted.
General admission to this course
Required prior knowledge
- A relevant BEng or BSc degree in a subject closely related to the content of the course or specialized program in question, such as aerospace engineering, aeronautical engineering, mechanical engineering, civil engineering or (applied) physics.
- If you do not meet these requirements because you do not have a relevant Bachelor's degree but you have a Bachelor's degree from a reputable institution and you think you have sufficient knowledge and experience to complete the course, you are welcome to apply, stating your motivation and reasons for admission. The faculty of aerospace engineering will decide whether you will be admitted based on the information you have provided. Appeal against this decision is not possible.
Expected prior knowledge
In addition to the entry requirements mentioned above, prior knowledge of the topic is necessary in order to complete this course. For admission purposes, TU Delft will not ask you for proof of this prior knowledge, but it is your responsibility to ensure that you have the sufficient knowledge, obtained through relevant work experience or prior education.
To view the essential background knowledge, please check your knowledge against the learning objectives of these comparable TU Delft courses:
