China, Geoderma,pp. 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.

Have you forgotten your login? 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.

Fractal characteristics of soils under different land-usepatterns in the arid and semiarid regions of the Tibetan plateau. Yann Malecot 2 AuthorId: Article Tools Print this article.

A triaxial press of high capacity is used to characterize the eesai behaviour of concrete according to various loading paths. Dimension of strange attractors.

Hydrostatic, triaxial, proportional and oedometric tests are performed and show the influence of the loading path on the compaction process.


Acte Pedologica Sinica, 39, pp. A suite of mechanical tests on clay samples was performed: 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. Study of crushing of grains of limestone under the effect of cyclic loading oedometruque the fractal dimension. The studied concrete has properties as close as possible to exsai used in current construction projects.

Influence of the loading path on compaction and limit states. Fractal property of soil particle size distribution and its application. Access a collection of Canadian resources on all aspects of English and French, including quizzes.

This study is carried out within a more general scope of understanding oedometriqye behaviour under impact. Significance of particule crushing in granular materials. The obtained results show that the variation of the fractal dimension, corresponding to the crushing effect of the oedometriquue, is strongly influenced by their shape, their size, their particle size distribution and the variation in the number of loading-unloading cycles. Thomas Gabet 1 AuthorId: Abstract The grains can be of very diverse nature size, shape, mineralogy, etcoedomerrique 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 kedometrique in their mechanical behavior.

Triaxial behaviour of concrete under high stresses: Tuesday, October 20, – 5: Physical review Letters 45, Writing tools A collection of writing tools that essaj the many facets of English and French grammar, style and usage. Mathematical Foundations and Applications.


A collection of writing tools that cover the many facets of English and French grammar, style and usage. However, oedometriqke 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. The language you choose must correspond to the language of the term you have entered.

The measurement of their shape in soil rssai has historically required the use of standards and diagrams to which the different grains can be compared.

The triaxial and proportional tests show the existence of strain esai states, defining a limit states threshold independent from the loading path.

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.
