Cai Chengwu. On Analytical Solution of Rotationally Periodic Structures[J]. Acta Scientiarum Naturalium Universitatis SunYatseni, 1986,25(2):64-72.DOI:
The continuous system with rotational periodicity is considered.Some exactsolutions are obtained for following problems:(1)The forced vibration forthe polygonal frame which is simply supported at each nodal point.(2)Thenatural vibration and buckling problem for the prismatic shell whose normalcross section is a polygon.
