Preceding to this transition, the solution exhibits a partial symmetry breaking at Ra = 550; a loss of symmetry with respect to the diagonals in each horizontal plane. In these steady state flows, the rising and sinking motion near the lower and upper boundaries shifts slightly to off-diagonal...
The stability of such motion is investigated when the body rotates at constant angular velocity around the vertical, while its centre of mass moves between collisions on a parabola or along a fixed vertical line coinciding with the axis of rotation of the body. Stability conditions are obtained ...
The earth pressure distribution method is designed on the following principle: using model symmetry, the σx and σy of measuring places in the range between two piles of three model piles in the middle are determined. Finally, the findings are aggregated into a single range between piles, ...
