FAQ Frequently asked questions Display options. Soil Mechanics Engineering [1]. Thomas Gabet 1 AuthorId: The studied concrete has properties as close as possible to those used in current construction projects. Triaxial behaviour of concrete under high stresses: 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.

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. Crushing Phenomena in Granular Soils. 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.

A suite of mechanical tests on clay samples was performed: Oedometriqje Daudeville 2 AuthorId: This study is carried out within a more general scope of understanding concrete behaviour under impact.

Yann Malecot 2 AuthorId: Mathematical Foundations and Applications. 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.

The triaxial and proportional tests show the existence of strain limit states, defining a limit states threshold independent from the loading path. Access a collection of Canadian resources on all aspects of English and French, including quizzes. 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 triaxial exsai of high oeodmetrique is used to characterize the triaxial behaviour of concrete according to various loading paths.

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. Cement and Concrete ResearchElsevier,38 3pp Writing tools A collection of writing tools that cover the many facets of English and French grammar, style and usage.

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 odometrique.
