Résumé

The Transfer Matrix Method (TMM) is extended to handle the transmission loss of finite stiffened and orthotropic structures lined by porous materials in a multi-layered configuration. The effects of curvature, stiffeners and heterogeneity are considered. The resulting model is easily adaptable to multi-layer configurations.
