In recent years, new metamaterials emerge one after another in various fields with various functions, showing a bright future for the development of metamaterials. Negative Poisson’s ratio material is one of the promising materials. It has a wide range of applications in mechanical engineering, acoustics and architecture science. This paper attempts to explore the different deformation mechanisms and possible applications of perforated plate materials with negative Poisson’s ratio. Finite element analysis is used to simulate a typical perforated plate structure, which shows negative Poisson’s ratio effect and abundant deformation forms in vibration condition. In addition to the existing applications in vehicle buffering and building noise reduction, this paper proposes that the perforated plate can be used as a filter screen for water treatment, as well as the filter screen of air purifier. In addition, it can also be used to cultivate precious herb seedlings. Intersects with the medical field, it can even manufacture the vascular embolization treatment device, which can ensure that the longitudinal does not contract and scratch the blood vessel when the blood vessel is opened. On the basis of this study, we can further study the special properties of metamaterials and solve the specific problems in various applications.
