项目摘要

This project is a cooperative effort between University of New Mexico (Dr. T.T. Ng) and Rennselaer Polytechnic Institute (Dr. Dobry) in which the objective is to use two- and three- dimensional random arrays of elastic rough quart ellipsoids for computer simulations of uniform sands. Good quantitative predictions for a wide range of strains, drained and undrained loading, and static as well as cyclic loading can be studied from these arrays. Micromechanical statistics of phenomena occurring at the particle/contact level will be obtained from the numerical simulations. Monotonic and cyclic laboratory axial/torsional tests on hollow cylindrical specimens of spherical and elongated glass beads as well as on sand will be done to verify numerical simulations.
这个项目是新墨西哥大学(Dr. T.T. Ng)和伦斯勒理工学院(Dr. Dobry)的合作成果,其目标是使用弹性粗糙夸脱椭球的二维和三维随机阵列进行均匀砂的计算机模拟。这些阵列可以对大范围的应变、排水和不排水加载、静态和循环加载进行良好的定量预测。在颗粒/接触水平上发生的现象的微观力学统计将从数值模拟中获得。将对球形和细长玻璃珠的空心圆柱形试样以及砂土进行单调和循环实验室轴扭试验,以验证数值模拟。
