## Investigation into elastic properties of anisotropic random foam model

• 摘要: 为了利用随机模型来分析泡沫材料微结构的各向异性对其力学性能的影响,在各向同性的Voronoi随机泡沫模型基础上,通过引入胞体生长速度的差异,得到各向异性的开孔和闭孔随机泡沫模型.利用有限元方法对模型的弹性性能进行了数值分析,得到相对杨氏模量和泊松比同各向异性尺寸比的关系,并和理论预测结果进行了对比分析.结果表明,建立的开孔和闭孔随机泡沫模型能较好地反映泡沫材料的各向异性力学性质;且开孔和闭孔泡沫的各向异性力学性能均与泡沫材料的相对密度有关.
