Mehrdad Massoudi, Tran X. Phuoc, " Modeling granular materials as compressible nonlinear fluids: Heat transfer boundary value problems ", Mathematical Problems in Engineering , vol. Box , USA. We discuss three boundary value problems in the flow and heat transfer analysis in flowing granular materials: i the flow down an inclined plane with radiation effects at the free surface; ii the natural convection flow between two heated vertical walls; iii the shearing motion between two horizontal flat plates with heat conduction. It is assumed that the material behaves like a continuum, similar to a compressible nonlinear fluid where the effects of density gradients are incorporated in the stress tensor.

This yield function is also known as the Warren Spring equation and experimentally-determined values of the shear index n indicate that n lies between the values 1 and 2. We extend the known Coulomb-Mohr solution for the indentation of a granular material by a flat rigid punch to the case of shear-index materials and we determine an associated velocity field assuming a previously proposed dilatant double-shearing theory.

The proposed solution is by no means unique and an alternative solution is noted in an Appendix which although a bonafide solution of the governing equations may not arise physically. Oxford University Press is a department of the University of Oxford. It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide.

It seems that you're in Germany. We have a dedicated site for Germany. Editors: Hill , James M. Granular or particulate materials arise in almost every aspect of our lives, including many familiar materials such as tea, coffee, sugar, sand, cement and powders. At some stage almost every industrial process involves a particulate material, and it is usually the cause of the disruption to the smooth running of the process. In the natural environment, understanding the behaviour of particulate materials is vital in many geophysical processes such as earthquakes, landslides and avalanches.
