Rapid drying can increase brittleness and induce internal cracks which predispose the product to breakage during subsequent activities. The drying process must be understood and controlled so that design guidelines which reduce or minimize drying damage to rough rice can be established and improved. This study is to give a mathematical model with numerical solution to follow the mass distributi...

In the process of geotechnical engineering excavation, wet and water-filled rock masses are inevitable. To obtain mechanical properties these rocks, indoor tests required, most dry or nearly dry. They cannot really reflect true nature rock, let alone its under a dynamic load. The was repeatedly impacted during blasting excavation process. determine response characteristics damage evolution rock...
