Zusammenfassung: | The combination of an auxetic structure featuring a negative Poisson’s ratio (NPR) and viscoelastic materials with superior damping behavior and energy absorption introduces a collaborative strategy that utilizes the distinct properties inherent in each category. This provides numerous advantages across various applications, enabling viscoelastic auxetic materials (VAMs) not only to resist deformation but also to dynamically adjust to changing conditions. In these regard, numerous investigations into constitutive models for VAMs have been conducted, exploring a range of structural architectures, materials simulations, experimental methodologies, static and dynamic performance, and practical applications. To clarify the unique potentials of VAMs in various fields, this review presents a summary of structural configurations and classification of materials, considering exceptional mechanical properties of the auxetic structure coupled with viscoelastic behavior. The objective of this study is to provide a comprehensive overview of numerical analysis and fabrication techniques, while also addressing the challenges associated with the implementation of viscoelastic-based auxetic structures and elucidating their capabilities. |
