STOCHASTIC AND DETERMINISTIC DYNAMICS INVESTIGATION OF THE MICROSTRUCTURE OF GRANULAR MATERIALS by Vishagan Ratnaswamy Granular materials are ubiquitous in one's daily life. They can be found in the cereal you eat, the sugar you put in your coffee or the sand you walk on in the beach. The study of granular materials has a rich history dating back to the 17 th century where Kepler studied the pa...

Granular materials, such as sand, gravel, grains, and salt, represent a large portion of the world around us, yet the dynamic behavior of these materials is not well understood. This lack of understanding is due, in large part, to the inherent difficulty in measuring the movement of and forces on individual particles. Computer simulations may be able to provide insight to this problem. Leveragi...

This paper proposes a new analytical procedure to simulate the frost heave of granular materials. The objective of the research is to examine the applicability of discontinuous analysis to numerical simulation for the mechanical behaviour of granular materials subjected to freeze-thaw action. In this paper, numerical simulations of freeze-thawing triaxial compression tests for glass beads were ...

We present experimental study of vibrofluidized granular materials by high speed photography. Statistical results present the averaged dynamic behaviors of granular materials in one cycle, including the variations of height, velocity and mechanical energy of the center of mass. Furthermore, time-space distribution of granular temperature which corresponds to the random kinetic energy shows that...
