This work first designs three hybrid auxetic honeycombs called Re-entrant-arrow-snake, Re-entrant-arrow and Re-entrant-snake. Then the analytical models of their out-of-plane bending properties are established, in which different connection boundaries are specially considered. By comparison, the established analytical models exhibit good agreement with the numerical models. Further, the bending mechanical properties of the hybrid auxetic honeycombs, including the bending stiffness and bending modes, are systematically studied. Results show that the hybrid designs can effectively modify the multidirectional bending properties of the auxetic honeycomb and significantly improve their designability. Especially, due to different deformation mechanisms, adjusting the inclined angle can dominantly affect the y-direction stiffness, and adjusting the height of the snake-shaped structure can independently adjust x-direction bending behaviors, thereby enabling its excellent adaptability across various engineering applications. This work provides significant guidance for designing and studying the bending behaviors of advanced hybrid auxetic honeycombs with multidirectional mechanical modifications, further promoting the applications of auxetic honeycombs in related fields such as flexible robots, flexible wings and biomedical stents.</p></div>","PeriodicalId":477,"journal":{"name":"Archive of Applied Mechanics","volume":"95 9","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144891406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this purpose, besides classical laminated plate theory, first-order and third-order shear deformation theory are employed. First, a closed-form solution is derived for the global buckling load of the stiffened plate, i.e., when plate and stringer buckle simultaneously. The solution is based on simple shape functions for the buckling mode in conjunction with the principle of the total elastic potential of the plate in the buckled state. Furthermore, a solution for the local buckling load is presented which is derived in a similar manner as the global solution. Lastly, a criterion for the determination of the minimum bending stiffness of the stringer is derived, i.e., a closed-form expression for the bending stiffness that is required to enforce a local buckling mode. Results for centrically and excentrically stiffened plates are presented which highlight the importance of the consideration of transverse shear deformations for thick to moderately thick plates, and comparative finite element computations show that the developed analysis approaches work with good accuracy and yet negligible computational effort.</p></div>","PeriodicalId":477,"journal":{"name":"Archive of Applied Mechanics","volume":"95 9","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00419-025-02917-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144888010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, we introduce a modified definition of the bandwidth along with a generalized approach that we use to develop exact expressions for the damping parameter of viscously and hysteretically damped single-degree-of-freedom systems under different inputs over a range of permissible amplitude ratios. When considering a direct force input, we find that the same closed-form expression can be used to determine the damping parameter from the displacement and acceleration FRFs. We also utilize this technique to establish exact damping parameter expressions for harmonic base excitation cases for the first time in the literature.
