Abstract

In this work, multilayer graphene was chosen and modeled in ANSYS software. In the software, it was subjected to bending forces through various bend angles. In order to test for bending, the model is subjected to rigid support on the base side. Then a force is applied on the side on which the angle is provided to simulate Bending. Stress–strain plots were analyzed for various bending angles. The graphene sheet was also subjected to twist forces within the software. In order to test for torsion, the model is subjected to rigid support on both sides. Then a couple is applied on the opposite sides to simulate torsion. Torsional stress and strain measurements were analyzed. The trends were studied and correlations with the material properties of graphene were established. The quest is to identify a magic angle for bend and twist.

多层石墨烯的弯曲和扭曲行为

在这项工作中，我们选择了多层石墨烯，并在 ANSYS 软件中对其进行了建模。在软件中，石墨烯通过不同的弯曲角度受到弯曲力的作用。为了进行弯曲测试，模型的底面要受到刚性支撑。然后在提供角度的一侧施加力以模拟弯曲。对不同弯曲角度的应力-应变图进行分析。软件还对石墨烯薄片施加了扭曲力。为了测试扭转，模型两侧都受到刚性支撑。然后在相对的两侧施加耦合以模拟扭转。对扭转应力和应变测量值进行了分析。对趋势进行了研究，并建立了与石墨烯材料特性的相关性。我们的目标是找出弯曲和扭转的神奇角度。
