Acoustic and shock loads

Acoustic loads can be applied only in transient or steady-state dynamic analysis procedures. The following types of acoustic loads are available:

  • Boundary impedance defined on element faces or on surfaces.

  • Nonreflecting radiation boundaries in exterior problems such as a structure vibrating in an acoustic medium of infinite extent.

  • Concentrated pressure-conjugate loads prescribed at acoustic element nodes.

  • Temporally and spatially varying pressure loading on acoustic and solid surfaces due to incident waves traveling through the acoustic medium.

The following topics are discussed:
