板格超材料是一种新兴的多功能超材料,具备超常的物理力学特性。首先,利用熔融沉积成型3D打印技术制备了不同晶胞长度、壁厚、开孔半径、晶胞层数的萤石结构板格超材料试样;然后,利用制备的试样进行了准静态压缩试验,并结合数字图像相关法和有限元仿真分析对比其变形机制,以探究不同参数对萤石结构板格超材料力学性能和吸能效果的影响。研究发现,无孔萤石结构在弹性区域内具有更高的弹性模量和屈服应力,表现出了更好的抗变形能力。随着晶胞长度的增加,能量吸收效率虽然提高,但比吸能会降低。壁厚的增加会导致弹性模量和平台应力上升,但比吸能降低。开孔半径的增加会导致平台应力和吸收能下降,比吸能降低。晶胞层数增加至3层时比吸能最高,但过多的层数会导致吸能效率降低。
Plate lattice metamaterials are an emerging class of multifunctional metamaterials characterized by exceptional physical and mechanical properties. Specimens of fluorite structure plate lattice metamaterials with varying cell lengths
wall thicknesses
pore radius
and numbers of cell layers were fabricated using fused deposition modeling 3D printing technology. Quasi-static compression tests were conducted on the fabricated specimens
and their deformation mechanisms were analyzed and compared through digital image correlation and finite element simulations to investigate the effects of different parameters on the mechanical performance and energy absorption capabilities of the fluorite structure plate lattice metamaterials. The study revealed that the fluorite structure without holes exhibits higher modulus of elasticity and yield stress within the elastic region
demonstrating superior deformation resistance. Although energy absorption efficiency increases with cell length
the specific energy absorption decreases. Increasing wall thickness results in higher modulus of elasticity and platform stress but reduces specific energy absorption. Enlarging the pore radius leads to decreases in platform stress and energy absorption
as well as a reduction in specific energy absorption. The specific energy absorption reaches its maximum when the number of cell layers increases to three; however
excessive layering diminishes energy absorption efficiency.
