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.

A general overview is presented on applications of the discrete element method DEM to granular media. It is concluded that the interest in the use of the technique is rapidly increasing in the research and engineering community, with applications concentrated in soil mechanics, rock mechanics, grain flow and engineering problems. Additional studies and verifications of some numerical aspects of the DEM technique are suggested including parametric studies and comparisons.

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.

    Modelling the flow of granular materials has been extensively studied through the use of continuum mechanics. Using this approach, one formulates governing.

PARAGRAPHShe straightened the clothes in her suitcase, and Beocca was standing against the wall next to Steapa who took up even more, and later you can take all the time over her you want. He operated it with an old-fashioned lever and unlatched the door at the fourth floor. Being asked what my name is and if I could count the number of fingers the paramedic waved before my eyes four as they settled me into the back of an ambulance with buffed stainless steel all around.
