To develop lightweight and biomimetic structural materials, in this paper, the compressive deformation and mechanical properties of the grid beetle elytron plate (GBEP) with the same core volume as the end-trabecular beetle elytron plate (EBEP) under compression were investigated for the first time. (1) The B-type deformation mode of trabeculae is clarified, which is a higher stage of independent deformation than the Φ-type deformation mode in the beetle elytron plate (BEP). Additionally, the four deformation modes of the BEP are divided into three stages in succession from easy to difficult: C-type, Φ-type and S (B)-type deformation. This paper verifies that the compressive strength and energy absorption capacity of the GBEP increase by 35% and 87%, respectively, relative to those of the grid plate (GP) with the same volume. (2) Although the number of trabeculae of the GBEP is significantly less than that of the EBEP, each trabecula in the GBEP has one more honeycomb wall constraint than each trabecula in the EBEP. The increase range of the compressive properties of the GBEP relative to the GP is greater than that of the EBEP relative to the honeycomb plate (HP). This confirms the prediction that the compressive properties can be effectively improved by appropriately increasing the constraints on the trabeculae. This paper deepens and enriches the knowledge regarding the biomimetic application system of BEPs, lays the foundation for GBEPs, whose preparation is convenient, and accelerates the applications of GBEPs.

一种新型的仿生格栅板—格栅甲虫电子快板的压缩变形和力学性能

为了开发重量轻且仿生的结构材料,本文首次研究了与压缩后的小梁甲壳虫elytron板(EBEP)相同的核心体积的格栅甲虫elytron板(GBEP)的压缩变形和力学性能。时间。(1)明确了小梁的B型变形模式,这是比甲虫elytron板(BEP)中的Φ型变形模式更高的独立变形阶段。此外,BEP的四种变形模式从容易到困难依次分为三个阶段:C型,Φ型和S(B)型变形。本文验证了GBEP的抗压强度和能量吸收能力相对于相同体积的格栅板(GP)分别增加了35%和87%。(2)尽管GBEP的小梁数量明显少于EBEP,但GBEP中的每个小梁比EBEP中的每个小梁具有更多的蜂窝壁约束。GBEP相对于GP的压缩性能的增加范围大于EBEP相对于蜂窝板(HP)的压缩性能的增加范围。这证实了通过适当增加对小梁的约束可以有效改善抗压性能的预测。本文加深和丰富了BEPs仿生应用系统的知识,为GBEPs的制备奠定了基础,其制备方便,并加快了GBEPs的应用。GBEP中的每个小梁比EBEP中的每个小梁具有更多的蜂窝壁约束。GBEP相对于GP的压缩性能的增加范围大于EBEP相对于蜂窝板(HP)的压缩性能的增加范围。这证实了这样的预测:通过适当增加对小梁的约束,可以有效地改善压缩性能。本文加深和丰富了BEPs仿生应用系统的知识,为GBEPs的制备奠定了基础,其制备方便,并加快了GBEPs的应用。GBEP中的每个小梁比EBEP中的每个小梁具有更多的蜂窝壁约束。GBEP相对于GP的压缩性能的增加范围大于EBEP相对于蜂窝板(HP)的压缩性能的增加范围。这证实了这样的预测:通过适当增加对小梁的约束,可以有效地改善压缩性能。本文加深和丰富了BEPs仿生应用系统的知识,为GBEPs的制备打下了方便的基础,并加快了GBEPs的应用。这证实了这样的预测:通过适当增加对小梁的约束,可以有效地改善压缩性能。本文加深和丰富了BEPs仿生应用系统的知识,为GBEPs的制备奠定了基础,其制备方便,并加快了GBEPs的应用。这证实了这样的预测:通过适当增加对小梁的约束,可以有效地改善压缩性能。本文加深和丰富了BEPs仿生应用系统的知识,为GBEPs的制备打下了方便的基础,并加快了GBEPs的应用。
