A parametric analysis of free vibration and bending behavior of sandwich beam containing an open-cell metal foam core

Free vibration and bending behavior of sandwich beams containing open-cell metal foam core are studied in the present work using zigzag theory. Hamilton's principle and the principle of minimum potential energy are applied for determining the governing equations for free vibration and bending behavior, respectively. Three types of distribution of pores are used during the present study. The influence of the distribution of pores, end condition, thickness of the core, foam coefficients on beam behavior is studied in detail. The face sheets are assumed to be made up of the same material like foam. It was noticed that the nature of the distribution of pores and the end conditions widely determine the behavior of the beam.

This study investigates the free vibration and bending behavior of sandwich beams containing open-cell metal foam core using zigzag theory. The governing equations for free vibration and bending behavior are determined using Hamilton's principle and the principle of minimum potential energy, respectively. Three types of pore distribution are examined in this study. The influence of pore distribution, end condition, core thickness, and foam coefficients on beam behavior is studied in detail. The face sheets are assumed to be made of the same material as the foam. It is observed that the nature of pore distribution and end conditions greatly affect the behavior of the beam.
