Systems and methods for improving direct numerical simulation of material properties from rock samples and determining uncertainty in the material properties
摘要：
A testing system for analyzing a 3D digital volume of a material sample. The testing system defines several test volume sizes with each test volume size including a different numbers of voxels, defining the size of portions of the 3D digital volume to analyze. For each test volume size, the testing system acquires two adjacent portions of 3D digital volume at the test volume size currently being analyzed. The testing system calculates a material property value for the two adjacent portions of the 3D digital volume, and a difference value between the two adjacent portions of the 3D digital volume. The process is repeated over the different test volume sizes. The testing system calculates mean difference values for the different test volume sizes, from which it determines a representative elementary volume.

用于分析材料样品的3D数字体积的测试系统。 测试系统定义了几个测试体积大小，每个测​​试体积大小包括不同数量的体素，定义要分析的3D数字体积的部分大小。 对于每个测试卷大小，测试系统以当前正在分析的测试卷大小获取3D数字卷的两个相邻部分。 测试系统计算3D数字体积的两个相邻部分的材料属性值，以及3D数字体积的两个相邻部分之间的差值。 该过程在不同的测试体积大小上重复。 测试系统计算不同测试体积大小的平均差值，从而确定代表性基本体积。
