The Department of Applied Mechanics conducts research in the areas of vehicle design and mechanical engineering. The research is often carried out together with national and international academic and industrial partners, and it concerns both fundamental and applied problems. The research at the Division of Dynamics at the Department of Applied Mechanics is directed towards various dynamic, vibration and wave propagation problems, also with coupling to other physical phenomena such as wear or piezoelectricity. Both fundamental and applied research is performed, and although the main thrust is towards modelling and numerical treatment, experimental activities also play an important role.
The division of Dynamics has a large teaching involvement giving basic courses in mechanics and strength of materials and advanced courses in mechanics, FEM, structural dynamics, and optimization of dynamical systems.
The Division of Dynamics at the Department of Applied Mechanics is seeking a new PhD student to start in the spring of 2011. The research will be conducted within the project described below.
PhD project: Nonlinear Computational Models for Aircraft Structural Dynamics
For aircraft flutter simulation, numerical stress evaluation and dynamic response prediction it is crucial that the used computational models represent the real structural behavior well. This can not always be achieved by the use of linear computational models that are the standard of today.
When results from laboratory vibration tests or from real flight mission tests are compared to their associated computational results, discrepancies are unavoidable. In this project we strive at decreasing such discrepancies. There are reasons to believe that many differences are due to nonlinear phenomena such as damping, dry friction, backlash, load dependent contact geometry and fuel tank sloshing.
The purpose of this project is to investigate methods that can be used to localize the causes of the discrepancies between test and computational results. This will be done by use of computational model updating methodology. Further, the project aims at increasing the knowledge of the nonlinear phenomena that are most significant for the aircraft dynamics and thereby necessary to include in the computational models. The project has a strong coupling to vibrational tests. These tests need to be informative with respect to model parameters. Studies of test procedures is a natural part of the project and test improvements may be found necessary for the characterization of nonlinear behavior.
A suitable background is a Master of Science (Swedish: civilingenjör) in mechanical engineering, engineering physics or civil engineering with emphasis on applied and computational mechanics. A strong interest in modeling, simulation and experimental validation of models is required.
Knowledge of the Swedish language is desirable but not a requirement. However, all PhD Students are expected to be able to teach in Swedish as well as in English after two years of employment. Those who do not have Swedish as their mother tongue are offered courses in the Swedish language.
The application shall be written in English and include the following items:
- An application of a maximum of one A4 page containing your specific qualifications for the position
- Attested copies of education certificates, including grade reports and other documents
- Curriculum Vitae
- Letters of recommendation and name of reference persons (optional)
The application shall be sent electronically as pdf or zipped documents. Please use the button at the foot of the page to reach the application form.
If any material is not available electronically or cannot be transferred to pdf format, the material can be sent as a hard copy to Registrar. The applicants name and the reference number (2010/264) must be written on the first page of the application.
