DEM Modeling of Vane Shear Test in Cohesive Solids
Abstract The vane shear test is used for obtaining the unstrained shear strength of cohesive soil in civil engineering. In present work, discrete element method (DEM) has been applied to build a numerical model to simulate the vane shear test. EDEM is a powerful DEM software, and it provides a cohesive contact model called Hertz-Mindling with JKR. In this literature, Hertz-Mindling with JKR contact model is chosen for the contact between soil particles. Comparing the results of simulation with the results of laboratory test, we can see that the torque changing with the rotation angle is qualitatively similar to the laboratory test. It proves that the numerical model is reasonable to simulate the vane shear test. And we can get the results about how the torque changes with the rotation angle.
