中文摘要：

经典弹性理论能否适用于静态颗粒物质是颗粒物理的一个基本问题．报道了非线性颗粒弹性方程对环柱几何（或称Couette几何）状样品中应力分布的计算结果．由于这些结果大都可在今后用实验直接测量，因而可将它们用于进一步判断这些弹性方程对颗粒材料的适用性以及澄清这个基本问题．另外，这些结果还可用于分析计算工程中的侧压力系数．

英文摘要：

Whether or not the classical theory of elasticity is valid for static granular matter is a basic question of granular physics. We present in this work stress distributions inside hollow cylindrical （Couette geometry） specimens, calculated with the nonlinear elastic equations recently reported in literature. Most of these results can be experimentally measured, and are useful for clarifying the basic question by testing the applicability of the nonlinear elastic equations to granular matter. Moreover they can also be used for analyzing the lateral pressure coefficient of interest in soil engineering.
