Based on these parameters used for the repose angle test and direct shear stress test, the value of repose angle is 31.97掳, the internal friction angle is 27.61掳, and the cohesive force is 33.06 kPa. The relative errors with the actual measured values are 9.5...
Detailed expressions for other forces are given in Table1. Specifically, the virtual mass force is a result of the acceleration or deceleration of the particle: the particle experiencing the acceleration or deceleration will influence the state of the surrounding fluid, which can be regarded as a ...

Full size table As an intrinsic characteristic of bulk materials, stacking angle can provide insights into their flow and friction properties27,28,29. A combinatorial approach11 was employed to calibrate parameters. Injection...
Among them, measuring the angle of repose is the most commonly used method (Bhupendra and Goswami., 2017). It is mainly used to determine the friction coefficient of hard or non-viscous soft particles, such as seeds or dryland soils. For cohesive soil, some experts and scholars used direct...

In this paper, the parameters between maize seed particles and soil particles are calibrated by means of angle of repose tests. Firstly, a sensitivity study is carried out on the contact parameters to be artificially input into the EEPA model using the Plackett–Burman test. Then, the ...
Liao et al., simulated the angle of repose (AOR) and shearing failure test on the stalks from the harvest stage of feed rape using the DEM. The contact model parameters were calibrated by establishing the regression model of the AOR and shear force [21]. Ren et al., used the response...
