Spherical inclusions RVE mesh models (periodic and non periodic)

The spherical inclusion models are generated through an iterative process with a Volume fraction ranging from 18% to 35%. The particle radius is set as a constant equal to r = 10µm. No interpenetration is permitted between each particle. The RVE width is Wp = 50µm for the periodic models. For the non-periodic, the cubical domain of each periodic model is cropped to a smaller width Wnp = 38µm < Wp − r/2 such that the periodicity constraint is annihilated. All the files are given in the .inp format from Abaqus. A classic RVE is provided with periodic models for them to be embedded. Along with non-periodic models, an enveloped RVE is provided with a thickness of 1 and a mesh density of 0,1.

本数据集涵盖的球形夹杂模型通过迭代流程生成，其体积分数范围为18%至35%，颗粒半径固定为r=10μm，且所有颗粒之间均不允许相互重叠。周期性模型的代表性体积单元（Representative Volume Element，RVE）宽度设定为Wp=50μm；针对非周期性模型，将各周期性模型的立方域裁剪至更小宽度Wnp=38μm，满足Wnp < Wp − r/2的条件，以此消除周期性约束。所有文件均采用Abaqus软件的.inp格式存储。配套提供了可嵌入至周期性模型的经典RVE；此外还一并提供了非周期性模型，以及厚度为1、网格密度为0.1的包覆式RVE。
