Having previously assessed the inherent anisotropicity of open-cell foams due to manufacturing processes, the development of tools to understand the underlaying physical phenomena that take place as to multifunctional performance tailoring is addressed. In this work, the mechanical energy profiling of multilayered configurations with anisotropic porous materials is acknowledged as an integral part of such numerical tools. The methodology consists in a plane wave approximation for anisotropic multilayered structures as a mathematical base for the development of an energy assessment tool. This tool discerns between the different physical phenomena within the assessed structure, which can be then referred to a discrete energetic study. Finally, an analysis of the dissipative response for anisotropic porous materials as a function of their material coordinate orientation is done.
