The paper deals with the numerical modeling of a fragmented composite applied to a low-frequency shielding application. The considered composite is made of a steel layer placed between two aluminum layers, and is obtained by cold roll bonding. A first numerical homogenization process is proposed to obtain a homogeneous material with effective properties. As this material has still to be discretized with a fine mesh to be considered in the numerical model, a second step based on the AMSL approach is then used to work with a onelayer mesh for the composite screen.
