摘要

本文对3D打印晶格夹层结构进行了理论分析、数值模拟和力学试验,研究了其屈曲性能。晶格结构包括体心立方(BCC)和菱形十二面体(DOD)两种。晶格夹层板采用alsi10mg合金材料,采用选择性激光熔化技术制造。对比结果表明,在特征尺寸相同的情况下,DOD点阵夹层板不仅具有更高的承载能力,而且在屈曲后阶段表现出比BCC型板更强的韧性。屈曲模式取决于单元胞的拓扑结构。对于BCC型板和DOD型板,屈曲形式分别为局部屈曲和整体屈曲。讨论了不同屈曲模态产生的原因。此外,还研究了两种板在屈曲后阶段的屈曲演化和破坏模式。

Experimental and numerical investigation on the buckling of 3D printed sandwich structure with lattice core
In this paper, theoretical analysis, numerical simulation and mechanical test on the 3D printed lattice sandwich structures are carried out to study the buckling performance. 2 types of lattice structures, body centered cubic (BCC) and rhombic dodecahedron (DOD) are included. The lattice sandwich panels are made of ALSi10 Mg alloy materials and manufactured using the selective laser melting technique. The comparative results show that DOD lattice sandwich panel not only has higher bearing capacity, but also shows stronger toughness in the post-buckling stage than BCC type panel, even they have the same characteristic size. The buckling mode depends on the topology of the unit cell. For BCC and DOD type panels, the main buckling modes are local buckling and global buckling respectively. The reasons of different buckling modes are discussed. Moreover, the buckling evolution and failure modes of the two types of panels in the post-buckling stage are investigated.
