This is an introductory course into some aspects of the physics of granular materials. Three theoretical questions are looked into more detail corresponding to the 3h of the course: I present some statistical models to describe the shape of a heap under impact and present a way to calculate the...

We present experimental and theoretical studies of the shape of heaps. In the simplest case one has a cone with an angle of repose. A simple 1d model is presented and solved analytically to obtain this angle from the properties of individual grains. This model is generalized to take into account...
