Abstract

Humans have always sought the optimal use of materials around them and, in this field, inspired by nature, have succeeded in inventing various structures. As one example, lattice structures, which are lightweight, strong, and stiff, are used widely in various applications, including energy absorbers. Lattice structures with a negative Poisson's ratio have been developed as a new type of lattice structure. As a result of this feature, auxetic structures have unique properties like shear strength, penetration resistance, fracture toughness, crack resistance, and high energy absorbability. In this paper, the mechanical behavior of the auxetic panels made using the 3D metal printer method is investigated by experimental tests and finite element methods. Experiments are used to verify the accuracy of the numerical model. Using the DMLS method, samples were prepared from metal-based AlS10Mg Aluminum composition. The 3D printing method was used to fabricate samples. Afterwards, experimental tests were made and the mechanical properties of these materials were determined by tensile test and used in finite element simulations. Following the confirmation of the model's accuracy, the finite element simulation results are used to perform a parametric study and determine the appropriate geometry. The numerical analysis is conducted using ABAQUS software, which uses the nonlinear finite element method.
人类一直在寻求对周围材料的最佳利用,在这一领域,受大自然的启发,成功地发明了各种结构。例如,晶格结构轻、强、硬,广泛应用于各种应用,包括能量吸收器。负泊松比晶格结构是一种新型的晶格结构。由于这一特点,结构具有独特的性能,如抗剪强度、抗渗透、断裂韧性、抗裂性和高能量吸收性。本文采用试验试验和有限元方法对金属3D打印技术制造的消声板的力学性能进行了研究。通过实验验证了数值模型的准确性。采用DMLS法制备了金属基AlS10Mg铝组成的样品。采用3D打印的方法制作样品。然后进行了实验测试,通过拉伸试验确定了材料的力学性能,并进行了有限元模拟。在确认模型的精度后,利用有限元模拟结果进行参数化研究并确定合适的几何形状。数值分析采用ABAQUS软件,采用非线性有限元法。
