+ | In the videos below, the comparison of the flow with different value of friction and yield stress is shown. In the first video, concrete has yield stress equal to 40 [Pa] and plastic viscosity 40 [Pa.s], while friction parameter is equal to 10.0 and 80.0. In the second video, friction parameter is in both cases equal to 20.0 and plastic viscosity to 40 [Pa.s], while yield stress is 40 [Pa] and 400 [Pa]. | ||
