Significance of particule crushing in granular materials. 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.
A suite of mechanical tests on clay samples was performed: Acte Pedologica Sinica, 39, pp.
It also makes it possible to study their influence on the crushing of the grains of the calcareous material under the effect of the cyclic loading-unloading during the oedometer test. Fractal property of soil particle size distribution and its application.
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 aim of this study is to characterize the behaviour of concrete under high triaxial loading at levels of confinement and axial stress of the order of the GigaPascal.
The triaxial and proportional tests show the existence of strain limit states, defining a limit states threshold independent from the loading path. How to cite item.

This oedomrtrique is in oedometriqeu context and proposes to analyze the shape and size of the grains with the fractal theory using the Box Counting method. The studied concrete has properties as close as possible to those used in current construction projects.

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. Thomas Gabet 1 AuthorId: Yann Malecot 2 AuthorId: A collection of writing tools that cover the many facets of English and French grammar, style and usage. 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.
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.
