THE INFLUENCE OF THE MICROSTRUCTURE’S CHARACTERISTIC DIMENSION OF A LOOSE MATERIAL ON A ONE-DIMENSIONAL LIMITING STRESS STATE OF A HALF-SPACE
The one-dimensional limiting stress state of thin vertical cylindrical layer filled with a compressible loose material under vertical load is considered. The expressions for the components of the stress tensor are obtained. It follows that there is a linear distribution of vertical stresses due to its own weight. It is shown that the microstructure has no effect on the stress state under the assumed kinematic conditions. The plastic deformation area of the material is estimated according to the internal friction and rolling friction in a representative element.
