Abstract

The implementation of the free edge condition on an air-saturated open-cell porous layer was discussed. The different hypothesis and the finite element implementation of the free edge condition were also discussed. It was found that the measurements and the numerical results for the elastic foam were in good agreement with respect to each other.
