Nontrivial solutions of the asymmetric beam system with jumping nonlinear terms.
Numerical exponential decay to dissipative Bresse system.
Numerical study of acoustic multiperforated plates
It is rather classical to model multiperforated plates by approximate impedance boundary conditions. In this article we would like to compare an instance of such boundary conditions obtained through a matched asymptotic expansions technique to direct numerical computations based on a boundary element formulation in the case of linear acoustic.
