Abstract
Metamaterials with a porous structure possess a number of advantageous properties, including low mass, high specific strength, and a high energy absorption rate. When subjected to impact or compression, these materials exhibit excellent mechanical properties, which has led to their use in a variety of aerospace applications in recent years. In comparison with traditional porous materials, metamaterials possess mechanical and physical properties that traditional materials lack. This distinguishes them from traditional materials and provides new ideas for solving engineering problems. Starting from this deformation mechanism of concave contraction of such structures, this paper details the modeling of several types of porous negative Poisson's ratio superstructures, such as honeycomb, foam and tubular structures, and focuses on the mechanical properties of porous structures in terms of elasticity, impact resistance, and energy absorption when subjected to external forces. The paper commences with an exposition of the mechanism of negative Poisson's ratio effect of porous structure, accompanied by a discourse on the extant research status of several prevalent types of porous negative Poisson's ratio superstructures. Thereafter, the deformation mechanism of porous negative Poisson's ratio metamaterials under compressive load and impact is examined. conditions is introduced, and finally, the practical application of porous negative Poisson's ratio metamaterials in the fields of automobile industry, shipbuilding and other engineering fields are summarized, and the future of porous negative Poisson's ratio metamaterials is reviewed based on the existing research results. Finally, the practical applications of negative Poisson's ratio metamaterials with porous structure in engineering fields such as automobile industry and shipbuilding are summarized, and the future development trend and application prospects are prospected based on the existing research results.
