- | In the videos below, 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 400Pa. | + | {{video> |
