Abstract
This study primarily examines a badminton sport plate which is modeled as a rectangular plate and is enabled by graphene-origami metamaterials (GOMMs). The model’s bending performance is examined regarding weather conditions, especially temperature and humidity variations. To enhance accuracy, a new quasi-three-dimensional shear and normal trigonometric theory is employed. This new hypothesis accommodates transverse and normal strains. Differential equilibrium equations are derived by virtual displacement principle and subsequently a closed-form solution is provided to reach the results. The primary objective of the study is to investigate the impact of different conditions on bending behavior of the under-evaluation model. The findings demonstrate that the incorporation of GOMMs enhances the rigidity of the structure and, as a result, its deflection reduces. Conversely, when the temperature and humidity increase, the deflection enhances too.
期刊介绍：
Since 1965, the international journal Acta Mechanica has been among the leading journals in the field of theoretical and applied mechanics. In addition to the classical fields such as elasticity, plasticity, vibrations, rigid body dynamics, hydrodynamics, and gasdynamics, it also gives special attention to recently developed areas such as non-Newtonian fluid dynamics, micro/nano mechanics, smart materials and structures, and issues at the interface of mechanics and materials. The journal further publishes papers in such related fields as rheology, thermodynamics, and electromagnetic interactions with fluids and solids. In addition, articles in applied mathematics dealing with significant mechanics problems are also welcome.
