| Abstract: | The paper investigates the distribution of contact forces in a three-dimensional granular pile submitted to a compressive load, makes a half-quantitative analysis of the statistics, analyzes the transferred character and the relation between impresses and the pressure, and changes the rule of the asymmetric degree and probability density. Moreover, the reason for the conduction of the Daraboloid type is explained. |
| Keywords: | granular pile force distribution side peak arching effect |
