Vibroacoustic optimization using the coupled finite element and boundary element method

Reducing the vibration and noise level of structures has become an important task in engineering. An efficient tool for this job is the topology optimization. In this context, the topology optimization using the density-based approaches is applied to decrease the sound radiation from vibrating structures.

Research Topics:

  • Finite and boundary element method (FEM / BEM)
  • Acoustic topology optimization
  • Numerical vibroacoustics
