The Institute of Structural Analysis plays a central role in the education of civil engineers; almost all structural disciplines such as timber engineering, steel structures, and concrete construction rely on concepts from structural analysis. The courses offered by the institute cover the whole span from conventional calculations to computer-based simulation methods such as the finite element method. Research at the institute has its focus on simulations in fluid and structure mechanics. The fields of application can be summarized as follows:

In most applications, interfaces play a central role. They occur in the context of crack simulations, multi-field problems (e.g., two-phase flows), and multi-physics problems (e.g., fluid-structure-interaction) just to name a few. Dealing with interfaces poses various challenges to simulation schemes and requires innovative and advanced approaches. The institute works on various different numerical methods (FEM, XFEM, isogeometric analysis, fictitious domain methods, meshfree methods, BEM) and the developed software libraries are used for research as well as teaching purposes.

These topics play also a central role in the research activities of the institute which include

  • computational modeling of vesicle-mediated cell transport,
  • multiscale biomechanical investigation of human aortas, and
  • mathematical modeling and computer simulation of aortic dissection.

In order to address these issues, biomedical investigations and mechano-mathematical models are combined with highly efficient numerical methods, novel multiscale constitutive models that incorporate nanoscale, microscale and macroscale mechanisms are derived, and predictive models for patient-specific simulations are developed. On the computational side, the institute applies and develops numerical methods for solid mechanics, fluid-structure interaction, nonlinear finite element analysis, and multiscale modeling. The developed constitutive models are implemented in well-established software packages such as FEAP and Abaqus in order to ensure an effective treatment of the problems.

E-mail: t.huenduernoSpam@tugraz.at

The Institute of Mechanics provides the basic education in mechanics, mechatronical systems, and multibody dynamics for students from Mechanical Engineering, Mathematics, and Biomedical Engineering. Advanced courses address nonlinear vibrations and topics on flight simulation. Experiments are used among other things to illustrate the content of the lectures in a compelling manner. Research activities at the institute are manifold and include the following fields:

  • Multibody dynamics
  • Nonlinear vibrations
  • Dynamics of machinery
  • Dynamics of vehicle systems
  • Contact mechanics
  • Mechatronics of vehicles
  • Flight mechanics
  • Flight simulation and robotics

The main objective is the development of fast algorithms to simulate large mechanical or mechatronical systems. Hence, the models employed should be as simple as possible and as accurate as necessary. To achieve an optimal balance, experimental investigations have to be carried out to examine special physical effects and to study the behavior of the real system. The laboratory of the institute  provides the facilities necessary for such experiments. Altogether, this allows the institute to connect theory, numerics, and physical testing.

E-mail: sekrnoSpam@fluidmech.tu-graz.ac.at

The institute is active in teaching and research in the fields of fluid mechanics and heat transfer. Teaching covers both theoretical methods and technical applications. Advanced courses are given on numerical and analytical methods in fluid mechanics and heat transfer and gas dynamics, as well as flow measuring techniques. For research, the institute is structured in four working groups:

Research includes the formation and dynamics of multi-phase flows from complex liquids, the elongational rheometry of viscoelastic fluids, aerodynamics of vehicles and ski jumping, computation of turbulent flows with chemical reactions, heat transfer with phase change, particles at interfaces and the collision of liquid drops and jets. Direct collaboration with industrial partners is strongly emphasized. Among others, the institute has the following experimental facilities: two wind-tunnels, (optical and thermal) flow measuring devices, a parallel computer, and various laboratory equipment. Numerical simulations address problems from the formation of thin liquid films on rotating plates and flows with heat transfer at high Prandtl numbers, to incompressible external and internal flows, such as turbulent channel flows. Another emphasis lies on the modeling of heat transfer with flow boiling. The simulations are performed using in-house software tools as well as commercial packages. The results are validated by experimental data.
