Computational Aspects of Structural Acoustics and Vibration
Invited Lecturers
- Jean-Pierre Coyette (University of Louvain, Louvain-la-Neuve, Belgium)
5 lectures on: Finite/infinite element techniques for acoustic radiation and scattering, modelling porous material using u-w and u-p formulations, handling visco-thermal effect in thin acoustic layers, random vibro-acoustics, acoustic transmission, energetic aspects of finite element methods, link between FE and SEA, acoustic propagation in non-isothermal conditions. Aspects related to boundary integral formulations and BEM for acoustics will be covered.
- Carlos Felippa (Univ. of Colorado at Boulder, Boulder, CO 80309-0429, USA)
5 lectures on: Partitioned simulation of coupled systems.; Monolithic and partitioned solution methods, Design of partitioned methods by the model system approach, Stability and accuracy analysis, Application to structure-structure and structure-control interaction, Application to exterior acoustic FSI: shock and vibration.
- Frank Ihlenburg (HAW Hamburg - Maschinenbau und, Hamburg, Germany)
5 Lectures on: Vibroacoustic simulation with automotive applications; Modal analysis (in the sense influence of modes and modal superposition). Medium freq range (possibly in context with FE error analysis; exposition of the problem, FE approaches – no hybrid SEA-FE methods!). Impedance condition, including the relation to absorbing BC for exterior problems. Industrial examples and validation, questions regarding acoustics.
- Roger Ohayon (Conserv. Nat. Arts & Metiers, Paris Cedex 03 , France)
6 lectures on: Covering interior structural acoustics linearized equations for an elastic structure containing an inviscid fluid. Choice of state variables. Corresponding variational formulations. Discussion on the symmetry of the formulations. Finite element discretization and reduced order models for modal analysis case.
- Niels Olhoff (University of Aalborg, Aalborg East, Denmark)
5 lectures on: “Structural design optimization against vibration and noise”: An introduction to structural topology optimization. Maximizing the fundamental eigenfrequency or the distance (gap) between two consecutive eigenfrequencies of structures. Maximizing the dynamic stiffness of structures subjected to forced vibration. Minimizing the sound power radiated from a structure into an acoustic medium (maximization will be also considered).
- Goran Sandberg (Lund University, Lund, Sweden)
7 lectures on: Basic finite element formulations for fluid-structure interaction, use of different variables, modal reduction of FSI, illustration of software implementation, hands on practise of examples to demonstrate the possibilities of FSI.
