Significance of particule crushing in granular materials. The studied concrete has properties as close as possible to those used in current construction projects. Glossaries and vocabularies Access Translation Bureau glossaries and vocabularies. Thursday, December 20, – 1: Soil Mechanics Engineering .
The measurement of their shape in soil mechanics has historically required the use of standards and diagrams to which the different grains can be compared.

The obtained results show that the variation of the fractal dimension, corresponding to the crushing effect of the grains, is strongly influenced by their shape, their size, their particle size distribution and the variation in the number of loading-unloading cycles. The fractal geometry of nature. Abstract The grains can be of very diverse nature size, shape, mineralogy, etcindeed even if each grain is a fairly simple object, the set of grains is a very complex system in which the geometrical and physical properties of the grains, their forces and their orientations play a crucial role in their mechanical behavior.
In which subject field? XPPp Crushing Phenomena in Granular Soils. In this test, the cylindrical sample as a whole can move only in the direction of its vertical axis and only in this direction can the pore water and the pore air be squeezed out.

This study is carried out within a more general scope of understanding oexometrique behaviour under impact. This work is in this context and proposes to analyze the shape and size of the grains with the fractal theory using the Box Counting method. A suite of mechanical tests on clay samples was performed: Email the author Login required. However, these methods are approaches and remain insufficient and incomplete for the actual measurement of their form and the understanding of their behavior remains a task far from being completed.

Study of crushing of grains of limestone under the effect of cyclic loading with the fractal dimension. Hydrostatic, triaxial, proportional and oedometric tests are performed and show the influence of the loading path on the compaction process. Freeman, San Francisco, pp.

Triaxial behaviour of oedometriqye under high stresses: The aim of this study is to characterize the behaviour of concrete under high triaxial loading at levels of confinement and oedlmetrique stress of the order of the GigaPascal.
