Functionally graded (FG) sandwich structures have garnered significant attention due to their potential in lightweight engineering applications. Porosity, a common feature in many materials, plays a crucial role in determining the mechanical behavior of these structures. This article aims to analyze the influence of various porosity models on the mechanical properties of FG sandwich plates. Through a comprehensive review and comparison of different porosity models, insights into their effects on stiffness, strength and failure modes of FG sandwich plates are presented. The findings contribute to the understanding of material design and optimization for advanced engineering applications.
