The study analyzed the influence of random defects on plateau stresses of honeycomb materials with varied relative densities and established a computational model of honeycomb materials considering random defects. The results show that the plateau stress decreases evidently as the random defects increase, which is closely related to the relative density of honeycomb materials.

processing the material by crushing. This means that a good percentage of the stone will be fractured in the crushing process.The broken stones will embed into the surface of a gravel road much better than rounded, natural-shaped stone. It also means that the material resists movement under loads better and gives better strength

Crushing Principles of Mechanical Crushing

Crusher Operation • Relation between Feed size and Shape – The greater reduction ratio the worse particle shape. – Inter particle breakage improves shape. When crushing a bed of material weaker particles will break first. Flaky or elongated particles are weaker then round. – Breaking round particles gives flaky material. F l a k i n e s ...
