Abstract

In the current study, a FEM-based representative volume element (RVE) technique is used to evaluate the elastic modulus of recycled high-density polyethylene (rHDPE) filled spherical-shaped shaped silicon carbide (SiC). In the ANSYS 2019, the material designer (MD) module is used to generate a 3D RVE of 500 × 500 × 500 μm cuboid, with randomly dispersed spherical SiC particles (i.e., 10, 15, 20, and 30% volume fractions) inside rHDPE. The Young's modulus values extracted from the RVE technique at various volume % are substantially nearer to experimental data than other micromechanical models. The tensile performance of the composite is simulated, and it was noted that the maximum equivalent stress of 4.1133 MPa for rHDPE/30% SiC composite, which is decreased to 13.8, 7.8 and 6.8% for rHDPE/10% SiC, rHDPE/15% SiC and rHDPE/20% SiC composite respectively. The results are astounding for immediate application in the relevant field of interest.

摘要

在当前研究中，基于有限元法的代表性体积单元（RVE）技术被用于评估填充球形碳化硅（SiC）的再生高密度聚乙烯（rHDPE）的弹性模量。在ANSYS 2019中，材料设计器（MD）模块用于生成一个尺寸为500×500×500μm的长方体三维RVE，其中rHDPE内部随机分散着球形SiC颗粒（即体积分数分别为10%、15%、20%和30%）。从RVE技术在不同体积百分比下提取的杨氏模量值比其他微观力学模型更接近实验数据。对复合材料的拉伸性能进行了模拟，结果表明，rHDPE/30%SiC复合材料的最大等效应力为4.1133MPa，而rHDPE/10%SiC、rHDPE/15%SiC和rHDPE/20%SiC复合材料的最大等效应力分别降低了13.8%、7.8%和6.8%。这些结果令人震惊，可立即应用于相关感兴趣的领域。
