Tangential displacement in DEM

ngkhaiching2000

December 2019 in DualSPHysics v4.4

I am working on DEM module in Dualsphysics currently and I am curious on how DualSPHysics calculates the tangential displacement (delta_t) . Please see Equation (70) below:

I obtained the following equation from the DualSPHysics online manual:

68747470733a2f2f692e696d6775722e636f6d2f5445575435776c2e706e67

(70)

Can anyone shed some lights on how to compute tangential displacement (delta_t) in DualSPHysics? I am wondering whether it is calculated using the incremental approach?

Thanks.
