Data underlying the publication: Biomimetic toughening design of 3D-printed polymeric structures: Enhancing toughness through sacrificial bonds and hidden lengths

This publication main focus on the mechanical properties characterization of bio-inspired structures with sacrificial bonds and hidden lengths. The dataset contains the tensile test results of the overlapping curls structures investigated in this publication. Based on the tensile load-displacement curves, it is able to summarize the parameters discussed in the publication. Also the dataset of the bio-inspired structures with different materials are also represented for comparison.

本研究主要聚焦于带有牺牲键（sacrificial bonds）与隐藏长度（hidden lengths）的仿生结构（bio-inspired structures）的力学性能表征。本数据集收录了本研究中所考察的重叠卷曲结构的拉伸试验结果；基于拉伸载荷-位移曲线（tensile load-displacement curves），可梳理总结本研究中讨论的各项参数。此外，本数据集还提供了不同材料仿生结构的相关数据，用于对照分析。
