Compaction Variables and Compaction Specification
Compaction is a mechanical process in which an earthen material is made more dense. The densification occurs as a direct result of the mechanical loading, and is essentially complete at the end of the loading. Volume changes are incurred as a result of a reduction in the quantity of air voids— water content remaining constant. Since it is impractical to squeeze out all the air, the as-compacted...
متن کاملNumerical simulation of dynamic soil compaction with vibratory compaction equipment
Roller drums make use of various shapes and their dynamic compaction effect is achieved by different kinds of dynamic excitation systems. The bearing capacity of layered soil constructions can be measured during the soil compaction process. The finite element method has been applied for dynamic analyses using elastic models. For the realistic simulation of the dynamic compaction process it is n...
متن کاملNumerical Methods for Predicting Roll Press Powder Compaction Parameters
Large numbers of cohesive powders are compacted using a roll press. The principle of compaction is that particulate materials become a compact when they are subjected to high pressure. Experimental work was carried out on pharmaceutical powders [1] to determine the influence of operating parameters on the roll process compaction. Theses parameters are determined for a given powder and must be m...
متن کامل2 - D Compaction A Monte Carlo Method
In this paper we study the two-dimensional compaction of integrated circuit layouts. A curvilinear representation for circuit elements, specifically chosen to make the compaction efficient, is developed. A Monte Carlo algorithm with heuristic termination criteria was applied to a variety of designs. These experiments give running times for compaction that are consistent with a conjectured avera...
متن کاملCompaction Behavior of Isomalt after Roll Compaction
The suitability of the new isomalt grade galenIQ™ 801 for dry granulation and following tableting is evaluated in this study. Isomalt alone, as well as a blend of equal parts with dibasic calcium phosphate, is roll compacted and tableted. Particle size distribution and flowability of the granules and friability and disintegration time of the tablets are determined. Tensile strength of tab...
