When the medium has water content and stickiness, it is called an ideal granular medium; otherwise, it is called a nonideal granular medium. The granular media commonly studied are often nonideal, such as, broken ores, clays, sands, slurry and other granular or p

Something like seismic wave, vehicle running, machine vibration, piling, explosion, etc. could lead to liquefaction of saturated granules.. Vibration can partly, even fully, break saturated granules down. Vibration re

Introduction,sands, slurry, fine coals, cements, corns, etc. Especially, the broken ores and sands are usually applicable in this study.. With the development of modern engineering techniques, the fields involving the granular dynamics are rapidly increasing. The so-called dynamical forces are mainly produced by
