Dataset of additively manufactured architectured material

The following dataset contains the experimental and numerical investigation of compressive stress in foam-filled close cell architectured materials. Quasi-static compression testing was performed on filled and unfilled lattice structures at 5 mm/min to obtain stress vs. strain data. The data was used to calculate mechanical properties such as energy absorption and peak stress. For numerical investigation, tensile properties of parent material (PETG) and foam were obtained from ASTM D638-14 and ISO 3386-1 respectively. Elastic and plastic properties were extracted for PETG to simulate the mechanical behavior. Videos of compression testing and numerical simulation are included for comparison.本数据集包含填充泡沫闭孔结构化材料的压缩应力实验与数值研究。以5 mm/min的加载速率对填充泡沫与未填充泡沫的点阵结构开展准静态压缩试验，获取应力-应变数据。基于该数据可计算吸能能力、峰值应力等力学性能参数。在数值研究环节，基体材料（PETG）与泡沫的拉伸性能分别通过ASTM D638-14与ISO 3386-1标准测得。提取PETG的弹性与塑性性能参数以模拟其力学行为。数据集同时收录压缩测试与数值模拟的相关视频，供对比分析使用。
