Dataset of additively manufactured architectured material using MEX process

The following dataset contains the experimental and numerical investigation of compressive loading 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 load vs. deformation data. The data was used to calculate mechanical properties such as specific energy absorption, peak load, and crash force efficiency. 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.本数据集涵盖填充泡沫的闭孔结构化材料的压缩载荷实验与数值研究。以5 mm/min的加载速率，分别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，获取载荷-变形数据。基于上述试验数据，可计算比吸能、峰值载荷及碰撞力效率等关键力学性能参数。在数值研究环节，基体材料（PETG）与泡沫的拉伸性能分别依据ASTM D638-14与ISO 3386-1标准获取；同时提取PETG的弹性与塑性参数，以模拟其力学行为。本数据集同时包含压缩测试与数值模拟的相关视频，用于结果对比分析。
