本文研究静态颗粒集合体中子区域的平均应力计算，提出在边界穿过颗粒时，对特定应力分量和子区域可精确计算，否则给出误差界限。
AI 中文摘要
本文关注于在较大的静态颗粒集合体中，允许子区域边界穿过颗粒的情况下，计算其内部小子区域的平均应力。对于某些应力分量和某些类别的子区域，计算出了精确的平均值。本文还确定了哪些子区域的选择可以精确计算应力分量，并在条件不满足时，提供了误差的合理界限。
英文摘要
The paper concerns computation of average stress within small sub-regions of a larger static granular assembly, where the sub-region's boundary is allowed to pass through the assembly's particles. An exact average is computed for certain stress components and for certain categories of sub-regions. The paper also identifies those choices of sub-regions for which exact stress components may be exactly computed, but when these conditions are not met, provides reasonable bounds on the error.
