Storage of Cohesive materials in Silos Part 2: Parametric Study

摘要

The stress-strain relationships obtained in Part 1 were used in ten finite element analyses of wall pressues developed during the storage and discharge of coesive materials from a silo. The effects of friction coefficient and hopper opening on the normal wall pressures were examined. Friction between stored material and silo wall was the most important factor affecting wall pressures throughout the silo. When friction coefficient increased from 0.2 to 0.3, the normal wall pressure decreased by about 30% for shorts, and 23% for oat flour. The effect of the hopper opening was not as significant
