Abstract
The structure of foam materials is analyzed. It is noted that foam materials have different strain diagrams in uniaxial tension and compression. A simplified physical model in the form of a steel ring is proposed for multimodulus foam materials. The model was tested on a Walter + Bai AG LFM-L-1 testing machine. The deformation of the model was analyzed using the ANSYS Workbench software package taking into account the contact interaction between the elements of the model. The calculation results were compared with experimental data.
分析了泡沫材料的结构。泡沫材料在单轴拉伸和压缩时具有不同的应变图。针对多模量泡沫材料，提出了一种简化的钢圈物理模型。模型在Walter + Bai AG LFM-L-1试验机上进行了测试。考虑模型各单元之间的接触相互作用，利用ANSYS Workbench软件包对模型进行变形分析。计算结果与实验数据进行了比较。
