Homogenization of the vibro–acoustic transmission on perforated plates

作者：

Highlights：

• Vibroacoustic problem on perforated plate is replaced by transmission conditions.

• These implicit conditions are derived by homogenization of a transmission layer.

• Homogenized interface reduces computational effort to solve the global problem.

• The wave propagation FEM-model with the homogenized interface was validated.
